Looking for Pam square clock cannister

[BrianS]

I have a clock face and dome for a square pam clock.  I need the back can.  Does anyone have a roached out clock they would sell the casing from.  This is not going to be a fancy clock, just a father/son project so condition does not matter.  I actually tied in a bid for one on Ebay.  I have never tied on a bid before.  Other guy put his in first so I lost.
