Default WTB: pairs of output transformers

Hi,
I am interested in buying a few pairs of output transformers. SE or PP, will consider and combination of primary and secondary impedances. Not interested in ultra high end stuff, just your average Edcor, Hammond, James, Trancemdar, or similar OPTs. Please email me with what you've got and how much...probably best to keep it CONUS but would consider international shipping if the price is right. I have a few people who want some tube amps built so I plan to build around what I can get on a budget.
Thanks!

The 'mystery transformers' are from Chris Hurley, at the AX-84 co-operative amp project with multiple taps for primaries and secondaries.
At about 1/2 the weight of an Edcor 25 watt SE, they are still rather high end for guitar use, although perhaps lacking I'm the lowest registers.
From the website is this information from the label on the transformers, which are new unused.

Heyboer m-27 hts-7687 output
pri Brown=0
brn/yellow=2.5K
blue/yellow=4K
blue= 6K
sec black=0
yellow=4 ohms
green= 8 ohms
orange=16 ohms

I hope this helps. I got these for a Epiphone Valve Junior project with EL-34 and/or 6L6 or 6550 output choices.
I am sure it is a bit overkill for guitar, but SE needs a lot of current ,and heat is always a problem I'm these designs.
Selling these as well as the others listed for reasonable cost plus shipping.
Moving cross country and would rather not spend money shipping these back and forth.

Give me a few more days and I will post it in separate ad. Let's not hijack Doc's thread.
PS. Set transformers with open brackets may look like crap but they were custom made and not all that cheap . I've spent over $200 with shipping from far east . Hammond transformers will come with experimental hammond chassis attached
