A few years before he passed, my dad passed on to me his Model 29 from the late 1930s, or possibly 1940. It's pre-war for sure. On the tang are two T&D holes filled with set screws. I've seen examples online of model 29s with a tang peep sight and a 1939 reproduction Savage catalog lists the model 29 as available with a "Savage no. 30 ear peep sight" and a "Savage no. 31 folding middle site." Anyone have information on if these were Lyman sights and if so, what model? Thanks!
