Bill...

Not sure what you are asking. The 2095219 nose piece is matched with the 2095150 housing for a correct set up.

The 2875560 housing is matched with the 2875553 nose piece to be correct.

The 219 piece you show above is dated January, 1969. A12 build dates start somewhere in mid March, so this piece could be mated with a later dated 150 housing to be correct. It is a little early for the A12 cars in my opinion.
