Q: What are the different versions?
A: The WWI-era version has original features like a straight backstrap, large hammer, and lanyard loops. It is also the most recent of my models, and has the most refined fit and finish.
The M45A1 is a tan-colored modernized build, with an underbarrel rail, ambi thumb safeties, long beavertail, front cocking serrations, raised sights, and very fancy grips. The model quality is missing some refinements, though.
The original Modernized version (white, light gray, and black) is similar, but with a threaded barrel. It's an early build, so the model quality is worse. The guiderail tracks are triangular, resulting in a fairly loose slide.
The original Classic version (white, light gray, and black) is an M1911A1 configuration, but with a large trigger. It's also an early build, with triangular guiderail tracks, and rather simplistic textures.
Q: What are those extra panels at the bottom of the slide? How do I build the grooves?
A: Here's an illustration.
. And here are the valley folds.
Q: How do I fold the guiderails?
A: Like this.
Note that the narrowest face folds flat onto the widest face, forming a "shelf." The rest of it is a box. The M45A1 version has square guiderails, which are different, but are actually simpler, so you should be able to figure them out without needing a guide.
Q: How do I build the rail base on the modernized version?
A: Look at its front and back faces. They should provide an idea of how everything else is folded. Here's a picture.
Q: What are the "inner sections" of the slide (pg.2) and where do they go?
A: If the "bottom of slide" is a u-shaped half-tube, its "inner sections" are attached inside it, to the larger hatched areas. Their job is to keep the spring front cap and the barrel apart. Here's a photo.
Although covered by the bushing, they are partially visible from the front.
