I know this is an old thread but I didn't want to start a new one! I finally picked up a MAS 1936-51. Should see it in about a week. I've been considering one for a few years now but they never pop up when I have the cash......until now. I actually saw it at a dealer online a couple hours after they closed so I sent an email right away and had to wait til they opened this morning to see if they still had it. When I finally got through to the shop the guy chuckled and put me on hold for awhile. Upon returning to the phone he informed me that there were in fact 11 different emails from people saying 'I'll take it' but mine was the first and my call sealed the deal! To top it off, the price was more than decent and it was described as having the grenade attachment and being in excellent condition, all matching and having seen little use. I guess it was meant to be.
