It would not be ANY of those as it has the USA Base with the GIBSON USA stamped logo and the 12 pole holes.
Recently I purchased a 1994 historic R7 Goldtop. the original bridge pickup had been removed and it came in the case. It was replaced with this pickup. does anybody know what pickup this is it says Gibson USA on it and written in pink to the left is a 13.
