If it's a FW it will say so on the side of the barrel. Your rifle appears to be a shooter or a candidate for a custom build but has little collector value.
Its not a fwt. The receiver indicates it was made in 1954. It has aluminum bottom metal. Likely changed out by previous owner. The stock it's in is cheap, op doesn't even know how to spell shilen, so there's that. Is it a shilen, who knows? And no, your rifle is not a "custom". Sorry. If I had to put a price tag on it, It would be around $800.00 and hope for the best..
