I have seen many NOS slant-six chokes with the Holley lettering...there's one on my car now.

When doing the resto on my Scamp, it was nuts trying to find all the little oddball things for a six. My car had belonged to my Grandmother so it had not been messed with...which was a huge help. All the original stuff was there.

It did not help matters that our Scamp was built in Canada and had several little odd things that cars built here did not.
