Free Large condensers for large enlarger

Somewhere, so many years I've forgotten when or where, I acquired this set of condensers for a relatively large enlarger. There are four parts: two flat-on-one-side-and-curved-on-the-other-side glass condensers, a length of corrugated metal to space the two condensers, and a round aluminum chimney to hold it all together. The chimney has three cut-outs that are obviously designed to engage-and-twist with pegs on the enlarger itself. One of the condensers has a very small engraving at its edge saying "upper." There is no indication of manufacturer or provenance. The chimney is 6 5/8 inches wide and 3 11/16 inches high. Altogether it weighs about 5 pounds 1 ounce -- wrapping and boxing for mailing wound increase the shipping weight towards 6 pounds.

So, if anyone wants this item, you can have it for free. I only ask that you pay for shipping to your address from my zip code 22033 and also pay for me to purchase an appropriate box if I can't find one here at home. On shipping -- I would recommend wrapping each condenser individually and not placing them in the aluminum chimney -- once wrapped, they wouldn't fit anyway. I can send a few more photos if you PM me; I'd add them here but I always have a difficult time getting free or for sale images onto Photrio.

I would think it would be for a 4x5, but it does not look like a Beseler 4x5 or CB7 to me. Hopefully someone can ID it.

Pretty sure those are for an Omega "D" series enlarger, however I am unsure which exact enlarger.

Could be for the older the D II (not the D2).

I have an Omega DII V and these are identical to those on my enlarger.
