...where did he get the modle for the RL?

There are quite a few Army Surplus places where you can buy them, some of the bigger dealers sell them online as they have them. Mostly its just a shell used for training, or an expended one turned into a training shell. The little bit they stick inside that pops off a blank .22 cartridge is not sold with the RLs, not too sure you can get them that way, the surplus laws and such can be a little murky.

The training ones fire a 9mm, least they did for us at training. That one is one of the office wall hangers.

I was going to correct that and had not gotten around to it, must have been a bit tired when I first wrote that.

Not a model hun, the real thing. Just part of the wonderful life of a maker of fine tools.
