Armorer's Tools: Bore Viewers
 
 
It wasn't too long after someone discovered that a rifled bore improved accuracy that someone else figured out that keeping the bore clean was the best way to maintain accuracy. 

The Reflector, Mirror, Small-arms, .303-inch makes its first appearance in The List of Changes in British War Materials in March 1891 (LoC 6374). 

The drawing and text describe it as brass, with a glass reflector mirror set at 45 degrees and outfitted with a brass outer case attached by a brass chain.  We will define this description as a TYPE ONE bore reflector. 
 
The next entry is almost twenty-five years later, in December 1915 (LoC 17687) introducing Reflectors, mirror, S.A. (Small Arms), .303-inch-Adaptor, Mark I for use with the Canadian Ross rifle and the new Pattern of 1914 (P'14) rifle.

This reflector, with adaptor, is now officially approved for general use with all .303 inch arms.   We will define this description as a TYPE TWO bore reflector. 

TYPE ONE
 
TYPE TWO
 
 
The reflector, with adaptor (TYPE TWO) is approved for Naval Service in October 1917 (LoC 20131).  In August 1925 all reflectors, including those used for machine guns (LoC 7338) are restricted to issuance/use by armourers only. (LoC A-1184)

There is even less information about the makers of bore viewers than there is about oilers. Like the brass oilers, virtually all of these bore viewers are stamped with a manufacturer's code or initials. Surprisingly, with the exception of RSAF-Enfield, none of these production codes match any of those found on oilers.

We have collected a number of bore viewers with different marks.  These are organized by type and mark, followed by our comments and observations. We welcome any new information that you have to offer.  We are also very interested in acquiring bore viewers with any new marks.
EFD
Type One; RSAF Enfield inspection.  This unit, 1.6" in length, matches the description found in the 1891 LoC, although the 4" chain is one inch shorter than specified.  PIC
EFD
F
Type Two ; stamped EFD (RSAF Enfield) in 1/8" letters on the side of the hinge. The hinge is an exceptionally fine piece of machining. 1.6" case body with a 2.75" handle and medium gauge chain 5.5" long. This unit closely matches the description in the 1915 LoC for all .303 arms, including Canada's Ross Rifle. Broad arrow marked on case end and on handle. The handle hinge body is also clearly stamped with the letter F.  PIC
EFD
G
Type Two ; stamped EFD (RSAF Enfield) in 1/8" letters on the side of the hinge. Same as above except the handle hinge body is clearly stamped with the letter G.  PIC
EFD
M
Type Two ; stamped EFD (RSAF Enfield) in 1/8" letters on the side of the hinge. Same as above except the handle hinge body is clearly stamped with the letter M.  PIC
EFD
O
Type Two ; stamped EFD (RSAF Enfield) in 1/8" letters on the side of the hinge. Same as above except the handle hinge body is clearly stamped with the letter O.    PIC
LAUDER CO.
1915
Type One; stamped LAUDER CO. 1915 on center body cover and Canadian broad-arrow marked on the end.  Exceptionally nice workmanship; the body of this unit is 2.25" in length and the fine gauge chain is almost 6.5" long. We suspect that this unit was originally intended for Canada's Ross Rifle.  PIC
MMCC
1915
Type One; stamped MMCC 1915 in tiny 1/16" letters on the end along with an early style Canadian broad-arrow mark.  The body is 2.25" in length and the medium gauge chain is 6" long. Again, we suspect that this unit was originally intended for Canada's Ross Rifle.  PIC
MMCC
1915
Type Two; stamped MMCC 1916 in 1/16" letters on the end. Early style Canadian broad-arrow mark on the 1.6" case body.  The 2.75" handle has a well-crafted hinge; the medium gauge chain is 5" long. This unit closely matches the description in the 1915 LoC for all .303 arms, including Canada's Ross Rifle.  PIC
CFBC
1916
Type One; stamped CFBC 1916 in 1/8" letters on the end. Early style Canadian broad-arrow mark on the case body.  The body is 2.25" in length and the medium gauge chain is 6.5" long. We suspect that this unit was originally intended for Canada's Ross Rifle.  PIC
CFBC
1916
Type Two; stamped CFBC 1916 in 1/8" letters on the end. Early style Canadian broad-arrow mark on the 1.6" case body.  The 2.75" handle has a well-crafted hinge; the medium gauge chain is 5" long. This unit closely matches the description in the 1915 LoC for all .303 arms, including Canada's Ross Rifle.  PIC
GILBERT
Type One; Birmingham Small Arms Co. inspection marked.  This unit, 1.6" in length, matches the description found in the 1891 LoC, although the 6" chain is one inch longer than specified. This is the only unit ever reported with a BSA inspection stamp.  PIC
GILBERT
Type Two; stamped GILBERT in tiny 1/16" letters on the case body; broad arrow marked on case end and on handle. The body is 1.6" in length and the medium gauge chain is 5" long. The hinge is very similar to the EFD Type Two viewer, an equally sophisticated piece of tooling.    PIC
F&S
Type Two; stamped F&S in 1/8" letters on the hinge body; broad arrow marked on case end and on handle. The body is 1.6" in length and the medium gauge chain is 5" long. The hinge is a simple tab pinned in place.      PIC 
MANROY
F&S
Type Two; stamped MANROY on the outer case in two locations.  For a while we thought we had discovered another maker's mark - until we noticed F&S stamped on the hinge body. In all respects identical to the F&S above.  Lettering on case is first-class work, lined up and even. We surmise that MANROY is the name of the armourer.       PIC 
LW
1917
Type Two; stamped LW 1917 in 1/8" letters on the handle hinge base; broad arrow marked on case end and on handle. The body is 1.6" in length and the medium gauge chain is 5" long, the hinge very similar to the EFD Type Two viewer, an equally sophisticated piece of tooling.    PIC
LW
1918
Type Two; stamped LW 1918 in 1/8" letters on the handle hinge base; broad arrow marked on case end and on handle. The body is 1.6" in length and the medium gauge chain is 5" long, the hinge very similar to the EFD Type Two viewer, an equally sophisticated piece of tooling.    PIC
.22 CALIBER
Type One; stamped RoNo 616772 in 1/8" letters on the case; no broad arrow or other identifying marks. The medium gauge chain is made of stamped and folded links, unlike the simple round wire noted on .303 caliber bore viewers.    PIC
.22 CALIBER
Type One; Identical to the one above; no broad arrow or any other identifying marks whatever. The unit has the chain made from simple round wire noted on .303 caliber bore viewers.  PIC
.50 CALIBER
ELE Co Ld
1940
Type Two; Identical to the .303 family of viewers, except clearly marked VICKERS .5 INCH MG; broad arrow and Navy marked, dated 1940.  Maker ELE Co Ld. unknown.   PIC
