Topic: Can anybody identify these carbs?

[zoo mob]

Sorry for the crappy pic, came from a CL ad, they come with two spare motors for $100. Don't look like K1-K6 carbs I'm familiar with, could they be CR or something?

Those are pumper, accelerator pump, carbs. They're they same type that are on my bike and other 77-78 cb750's. I don't know a what else they were one. Do they have a PD41A, PD42B, etc. or something on the side the #4 carb.?

77/78 PDs with accellerator pump. for 750 K & F

 are the slides plated brass or black anodized?

Eh, no interest now I suppose. Thanks for the quick responses, guess I have to find my race carbs elsewhere.
