This is a discussion on Various questions (T-37, M-84, grenade sight) within the Bill Ricca forums, part of the Gun Professionals category; Mr. Ricca, I have some various questions for you.
Do you have any info on the history behind the development of the T-37 flash hider ...
Do you have any info on the history behind the development of the T-37 flash hider for the M-1 Garand? The Vortex thread I started had me thinking. The T-37 was the first prong type flash hider used by the military right? I know there was a prong hider for the BAR. Did this pre-date the T-37 or were they contemporaries?
My other question deals with the M-84 Scope. When the M-14 was initially fielded and developed, was this scope ever used on the M-14? Did they make a mount for it to fit, or did they just use 7/8 in rings?
Finally, was there a specific jig or tool used to locate the positioning of the metal backplate for the rifle grenade launcher for the M-14?
As far as the T37, it was in development circa 1952. The earliest known production is 1959 at SA. If you are a GCA member I did a several page article on the production of the T37, about 3 or 4 years ago, in The Journal. I have not looked into the BAR prong FH, but it was around by 1958/59 also.
The first scope used on the M14 was the M84. Ordnance made up a base to use the M1-C mount on top.
In one of the numerous TM's there is a drawing shown to construct a template for mounting the M15 sight on the side of the M14 stock.
I bought one of Fred's "Grenade Launcher" stocks for $25.00 and got a pretty descent walnut stock with the holes already there in the right location. When I mounted my M15 sight, the armature of the sight sat perfectly level with the stock when the sight was at the "zero" degree setting. You could tell the stock had been used to launch grenades. There was an obvious dark circular mark where the old sight base had been for many years and the stock was re-inforced with several of those brass repair screws around the selector cut-out area. If it was ever cracked there, you could not tell, ... it looked more like a preventative measure.
