I came across an ebay auction for impellers.  The guy said they were CP made for berkeley.

Any ideas of the quality?

Heres a purely "visual" side by side comparison ,these two "A" impellers are nearly "exactly the same" dimensionally , lets you see what you think ? this is kind of like a Coke vs Pepsi taste test? Tom

one is of an impeller as we recieve it from AT ,one is new out of the box (kit) the customer said he purchased from another manufacturer (exact vintage unclear ,may have been a couple years old then) ,These are both "new" aluminum alloy impellers ,never run at the time the pics were taken , The two sold at the time for ,within a few dollars of each other I would honestly appreciate your thoughts and comments please vote ? Tom

(please dont "cheat" and click on  the "properties" just be honest and say what you think about the appearance !)
Impeller 1

impeller 2

Very well could be an optical illusion, but I like the center of the impeller #2, cannot explain why, but impeller #1 looks like the same old same old...But #2 has an interesting looking "bell" shaped center cone that would IMHO build more centrifugal pressure at the middle of the impeller and I think it would stay loaded better.....

There is no doubt # 2 "looks" better. O.k. Tom spill it.lol

I say that Berkeley needs to get their shit together.

oh you big cheater Skip  Did you peek ? 

There is no doubt # 2 "looks" better. O.k. Tom spill it.lol

The #2 impeller is an American Turbine , what we proudly sell 

Seems like I remember that  at impellers are a cut higher than a berkley? Or is that just an at impeller for an at bowl??  Is a "aaa" an option for a berkley, without going to a HH?
