Carb Identification Help

[Eengers]

I recently acquired this set of carbs in the attached pictures, and would like some help identifying them. I got them with a bunch of other parts from a guy who had passed away and his brother and nephew were getting rid of everything. He had some old CB750 parts there, as well as a couple CB900 bikes, so maybe these went to those? No identifying model numbers I can find on them other than Keihin and that's it. Just trying to figure out what I have here.

Looks like CB750 to me. K2 (1972) at least, not sure which model then used those up to. Not quite as desirable as the early early model with the 4 pull cables out the top, but still worth a decent amount to somebody if you don't plan on using them yourself.

if you are on FB there is a Carb appreciation society page run by Randakk. Thousands of members and lots of bike carb knowledge.
