ID mystery spacer ???

Not sure what the the first spacer in the pic fits, but NOT a QJ or TQ. Probably a Holley 4165 Spreadbore.

I'm not so sure,I think spread bore Holleys were originally manufactured as replacements for QJ and TQ. I'm thinking this is a factory piece..
I haven't seen a 1 inch phenolic spacer for sale as an aftermarket piece.
