Wunderlich Tank Bases

Just purchased an older elephant bag from Wunderlich and it came with three (3) bases. I don’t need them so if someone can use them, $10 plus shipping (they are light fit in an envelope). The largest one came off a 1200 GSA, but not sure what they other bases fit (the smallest one doesn’t have a gas cap opening i.e. F or G 650?) The guys at boxer two-valve might be able to tell ya, but they have no numbers or tags on them.
