Vintage 1950s HP 910-26 Power Transformer 520-0-520v 6.3v for Tube Amp

Description

Up for sale here is this rare vintage Hewlett-Packard 910-26 power transformer.  This was removed from a Hewlett-Packard 206A audio generator.  It doesn't have any specs or useful ID on it, but the schematic for the 206A looks like this has secondaries of 520v CT and several 6.3v secondaries.  I am not 100% sure, however, so please take a look at the manual (available online) and decide for yourself.
This is a really nice vintage US-made power transformer, and is guaranteed to work for you.
It does have some light wear, a bit of missing paint, and a very tiny bit of light rust.  A few of the wires have some bare spots where the cloth covering wore through, so you'll want to cover that up with heat-shrink or something similar.
Please see my pictures for details and dimensions.
US shipping and handling is .  I accept Paypal.  If you have any questions, please ask.
