Help identifying (non-Ferrari) Shock Absorbers

Please forgive the non-F content, but the people who might know would be here most likely. Can someone help me identify the Brand/Model of these shock absorbers?:

I think that they are fairly high-end shocks being double-adjustable (the C-knob has 16 positions and the E-knob 18 positions if I counted correctly). Came on my restomod, but one of the shorter (rear) ones started leaking, and, when I contacted the IRS supplier, they indicated that it wasn't repairable. They sold me a pair of QA-1 Ultra Ride shocks for the rear, and I put the same on the front. Hate to just throw them all in the bin so was looking to put them on eBay for a minimal price to cover the shipping and maybe an hour of my time to hassle with the packing/mailing. Have two of the longer ones and one of the shorter one that I think are still OK (and would include the leaking short one, too):

Longer shock:
Extended length = 15.5"
Compressed length = 11.5"

Shorter shock:
Extended length = 14"
Compressed length = 11"

Bushings in the eyelets at each end use a .75" OD x 1.25" long metal sleeve (with 0.5" or 9/16" ID).

Please let me know if you know what these are (or if you want them ).

 

That would be my guess, too (since the same top spring perches fit both these shocks and my new QA-1 Ultra Ride shocks) -- but what model QA-1 shocks?
