Vintage 1956 Output & Power Transformer Set for 6V6GT PP tube guitar amplifier!

Description

Up for sale here is this set of two transformers--one power transformer and one output transformer.  These came from a small tube amplifier from 1956.  The power transformer is marked 68P028-5 549643 and is dated 1956, and the output transformer is marked 67P050-3 1005644 and is also dated 1956.  The output transformer was originally used to run two 6V6GT output tubes (not included).  The other tubes in the amp (also not included) were a 6X5GT rectifier, a 12AX7, and I believe a 6E5 eye tube.
I tested the voltages on the power transformer, and they are approximately:
Red to red striped wire 508VAC
Striped to brown 257v
Striped to yellow 250v
Yellow to brown 7.23v
This is with a 120vAC input.  Voltages are generally higher unloaded, and this is probably specced for a 115v input, so they will be a bit lower in actual use.  This should be perfect for a small 6V6 guitar amp, or who knows what else.  This has secondaries at 6.3v and 450vCT or so.
The power transformer mounting holes are about 2 inches and 1.75" apart, and it's about 3" tall.  The output transformer mounting holes are about 2 3/8" apart, and it's about 2.5" tall.
These are used with moderate wear, and are guaranteed to work fine.  I don't have any specs on these other than what's in the listing.
Please see my pictures for details.
