Original power brake 71 booster

Does anyone have picture of original assembly line 71 E body disk/ rear drum booster?

I have seen the check valve to be located on both the raised surface and the recessed surface on Nos boosters.

Any survivor 440 pics?

Thanks,
Glenn

well, this is the one that was on my cuda when I replaced it with a 70 Bendix I picked up...there is a NOS 71 in the box for sale in the E body parts for sale section page 6, I picked up a NOS 71 Midland Ross booster in the box a few months ago on ebay...I looked for a LONG time for one, looks the same as my old one and the one for sale here on moparts...can't believe I don't have a pic of the one I bought on my computer...
