I found a pre-64 Wichester .270 WCF Super-Grade. What is is worth..? I would rate it at about 80% to 90% over all. Stock is in very good shape but has a rubber pad. Action looks to be a matte finish barrel is blue. It also has a two piece scope mount not sure but, didn't the super grades have a side mounted scope..? The floor plate is marked "Super-Grade" I don't know if this will help but the SN# is 182XXX
The stock looks like this one..
