I have a number of Win 69as and Win 75s and except for the stock and the price, there is not much difference.

In 2014 I got a Win 75 sporter made in 1941 with a Lyman 57 rear peep sight with parts missing.

I called up Lyman 860 632 2020.
The woman figured out that I could not understand their diagram.... sent me the parts for free.... I think I got a senior discount. ...err maybe a senior moment discount.
