I was told by the seller that it was an aftermarket top made by a famous (his words) engine builder in the 50's or 60's. He could not remember who it was.
The middle one looks to be an automotive version of the the Time-Rite used to set the mag timing on aircraft engines. If so, that's a very good tool...
There's a thread from 2005 started by @DoggieBoy Johnson about the Creitz brothers in Oklahoma. If I knew how to show the link, I'd do it but, as I'm pretty computer illiterate, you'll have to look for it yourself.
A local friend is a Creitz expert. Bob was from here. If you would like to contact him pm me and I will set you up.
Maybe you could take pictures that are not close ups, and include the whole part, showing both sides of each. And take the tool out of the can, if it's in there, so we can see it. I bet lots of folks would recognize the other side of that bellhousing, if they saw it.
Here is what is in the can. I have a couple of these and some have different small parts. This one had the allen wrench, the others did not. Some look unused, some may be used.
I also got this from him. The front is empty and the reverser housing has a set of planetary gears in it.
do you have any more pics of the lower bellhousing? it looks to be possibly for an early extended bell Hemi, it say Drag Machines on it ans I know they made adapters for the early dual range hydros to extended bel Hemi, but have not seen the lower bellhousing before. Is there a starter mount?
I've got nothing useful, but from now on I'm going to tell people that my old girlfriends used to call me RamSonic.. Used to...….
I'm not going to say I've seen everything..but I've been around. Never seen that Creitz stuff. The carb top has part number CT-4. I wonder what CT-1 through 3 are? Really cool stuff. They made a low profile dual quad intake, maybe this was companion stuff. Love seeing new, old, speed parts..
Carb top looks like a dual inlet conversion for an afb carter. Other carb topper is like the air horn sold for Holley’s, supposed to smooth the airflow into the throat.
