Guys,
Thanks for very sound advice.
I am not an expert anyway to do restoration my self. Just wanted to have enough knowledge before taking this gun to a professional gunsmith. But usually the gunsmiths available here, don't care much about following the right procedures, so you have to guide them what to do and what not to do. For example, while doing a re-blue they excessively buff the barrels and ruin the edges and stampings. Some guys do the same to action and blue it!!
The most I may want to do myself is clean the action and try re-finishing stock, if I get the proper oil finish. Looking for answer on re-cut checkering?
Absolutely no intention of using 3 inch ammo in it. Have got a box of 2-3/4 40 gram no. 4s. Are they safe for this gun? Usually, will be using standard 2-3/4 loads.
It is difficult to ascertain the grade (0000) of steel wool available here. Is it ok to use fine wired brass brush instead for rust removal?
Do any parts within the action need greasing?
