FOR SALE: Columbia model A trunnion - $150

[FloridaClay]

Not long ago I purchased a trunnion assembly for a Columbia Model A cylinder phonograph in the hope that it might fit my model AT, whose trunnion has potmetal issues. I had to make a decision in a hurry, so did not have a chance to verify that one way or the other before buying. It didn’t fit the AT, so I am going to sell it. I wanted to give our Forum users first crack at it before putting it up on eBay, as nice ones do not come around very often.

It looks to me as though one screw might have been replaced, but it is otherwise all original and solid. The parts that should move do so freely. As you can see from the picture, I found the finish to be excellent once I had removed a century of grunge.

As you may know, at some point in its history Columbia turned to making trunnion assemblies out of potmetal and that became a huge problem as the metal broke down over the years. This one predates that change and IS NOT potmetal. The very few places where the plating is worn away at friction points shows what appears to me to be brass showing through.

If you need a trunnion for your Columbia A, you might wait a very long time before finding another one this nice. Please note that I do not warrant that this item will fit other Columbia models, inasmuch as I have no way to check that out.

I am asking $150, which is a little less than I paid for it without shipping cost added in. My price includes shipping by priority mail. If you want to buy it, send me a PM and I will send you the email address to use to pay by PayPal, which I prefer. Of course you can PM me with any questions you may have also.

Hey Clay!
I have always wondered if those would fit the AT. What are the differences, do you know?

I am sorry you had to buy one to find out that they are not interchangable.

The arms on the tail piece are not long enough to reach the feed screw and the reproducer sits higher on the AT.
