Does anyone know the scoring ring sizes for the Test Target that Colt used?
I thought it would be interesting to create one using my drawing tool, but my search is weak and I'm not seeing any information.
The target itself is apparently still available from Colt:

I believe these targets were included with pistols when sold, as I've seen a few examples with various for sale ads. Examples:
This last one is a screen shot out of a video on M1911A1 production at the Union Switch and Signal Company during WWII, showing what I am pretty sure is the same target, used for validating each gun at the factory.
The reason for the question stems from from looking over a copy of the "Federal Specification, Pistol, Caliber .45 Automatic: M1911A1", D-P-355a, September 16, 1964 I found online. This spec includes the specs on targeting and accuracy, but doesn't specify the "sighting image". I suspect this is the T-10 test target. I thought it would be kind of fun to shoot this target, and I can create one with my drawing tool, but I need to know what size the circles are.
By chance does anyone have one of these old T-10 or T-10A Test Targets, and would not mind measuring the rings for me?
I've looked at all the NRA B series targets already, in detail, and none of those sizes match up, including a B-2 50 ft slow fire or a modern B-8 repair center. Based on looking at a lot of photographs lately, I think the outermost circle is 9", exactly. If the target paper is 10x10, that would make sense. The center 10 ring is I think 1", and the others increase by 1", but I'm not 100% certain on that, either.
I've done quite a bit of searching on this, but so far the definition of this "T-10" seems to be eluding me.
