i am assuming it is a standard grade (24" barrel). if a FW, the barrel will be 22". prices vary greatly - if it has a recoil pad, perhaps sights missing, swivels replaced with swivel studs and wood and blue in average shape, it is a $600-800 rifle. if all original and in very good shape it may eclipse $1000. If it is a supergrade (black forend cap and supergrade stamped on the floor plate) then you need to get professional advice which mine is not.
You "assume" its a std wt? Damn you are good. Getting that from the op's excellent description. I have 6 pre 64 rifles, can you please look in your crystal ball and tell me what they are worth.
