I've an opportunity to purchase a standard model 54 Winchester in 30-06 that was made in 1927, for $500. I've personally not seen the rifle, other than pics, but seller claims rifle is in good to excellent condition. Rifle has a lyman peep sight installed. So, any problems with these early model 54s. For example, I understand Winchester changed to a one piece fireing pin around 1930 when they made changes to stock design of the model 54 around 1930. $500 seems a decent price to me. What are your opinions on this price?
