WANTED: Columbia Fall Off Crank

[phononut]

Hi There
I just bought my first Graphophone, the Model AT, and am really excited to get it working and restored It is missing a few parts which I am looking for: the slotted crank, the floating reproducer & the trunnion (I think that's the right word).

The crank may be in any condition, and I hope not to break the bank paying for it as I already probably overpaid for the machine.

Here is a photo of the crank, as well as a beauty shot of the AT

Thanks in advance
Brad
