If it was a stock 47 we'd be able to give you a better opinion of what it's worth and what you could do with it.

Being it's already modded, and not 100% how you'd want it, then all bets are off.

The one part that really concerns me, as mentioned already, is the frame clip job. Who knows how well it was done? Inspect it closely and if you have a buddy that has done this kind of stuff (who knows what he's doing) have him help. More eyes see more things.
