A lot of views, no answers, so I will try. As I remember, if you needed one, you called Tiger and told them what No. 1 you had, caliber, model, etc. and they would supply you with one. I do remember one list where they listed I.D, and height, but not sure where. You might call Brown bells, they might be able to help. Tiger is an interesting company to deal with. You can, or could, order a M77 wood stock. A No. 1 stock was factory replacement only, and only in same style as the gun was originally shipped. If you had a custom barrel on it, they would only restock it after regard doing it to factory specs, at your expense.
