There are a whole class of pistols like this one produced in Spain beginning in WWI, called "Ruby" pistols. They were produced in very large numbers. They all share very similar structures internally. In addition to the missing parts, your pistol has has an awful lot of surface damage, and while I admire the grip plates you've made, and your interest in restoring the gun to functionality, I have to wonder if it's really worth it. If the gun has some sentimental value, then certainly it's worth doing, but if you're thinking of selling, in its present condition I don't think you could get much for it, even with all its parts. Western Gun Parts might be able to help. But it's going to be difficult in Canada to find someone who can supply those internals. Listing your needs on the Equipment Exchange might help. Finally, you didn't mention it, but I hope you have the license for it. I see that you have a "Trader Rating", so you probably know that this is a "prohibited" pistol in Canada. If you don't have the license, you'd best contact CFC about the problem before you do anything else. Good luck with it.
