[Boatanchors] Any Interest: Collins Power Transformer 500VCT

[William]

Hello All,
I have at least 1 Collins power transformer, part number 672-2240-00, that looks to be NOS based on the very clean terminals. 
>From the identification plate:
Serial 3371Part No  672-2240-00Freq  50-60Phases   1V.A.  50Pri. V.105-10-15-20-25Sec. No. 1 V  500 C. T.  (no other secondary taps)Amp  .130 DCTest V  2500
4 1/2" tall (not counting terminals) x 3 1/2" x 4 1/2" (including flange).  Terminals are ~  1/4" as measured from the bottom of the flange.  Nice gray color.  Identification plate has red paint with the winged Collins logo.  Some shelf wear and someone wrote 'ok' on the top and 'B' on one side.  Made by Chicago Transformer (logo stamped at the base).
Weight is 5 1/2 pounds.  Would certainly fit in a 6x6x6 inch box if only 1 is purchased.  More than one could fit in a Medium Flat Rate Box and would cost ~$16 to ship.
Is $25 per transformer plus shipping ok?  I think I have 3, but need to check for sure.
Putting this out to the community to check for interest before heading to alternative selling sites.
Best Regards,
William
