If you can't find an existing one, Wenig has do-it-yourself stocks for about $100 in a choice of styles that will fit your gun. It would make a good winter project if you are prepared to final-fit it to your receiver, sand and finish it.
I am very aware of the value and price of a BT 100 stock.I speak with MDGW at least once a week. I have had several and still do. I know full well that 185.00 is a fair price for what you have. But what you have is not what I want. I need it for a Leos Pigeon Grade VI and I just don't want to refinish w/hi-gloss a non monte carlo with no figure and aftermarket hardware. There is a chance the forearm probably wouldn't work either because the later satin models rarely had ejectors. I probably shouldn't have put "any condition" in the post I guess its missleading. I Did't mean to insult you "Crowbar" or whatever your name is by not buying your stock No doubt it's a "dandy" it just doesn't happen to be what I am looking for. Good luck in you quest to sell them.
