Help Identifying Plastic Reels

Hi, I've been rehabbing a community darkroom (White River Craft Center in Randolph, VT, if anyone's local) and am in the process of sorting through the developing reels.

This darkroom has gotten a lot of donations over the years, so things have gotten a bit jumbled.

We have Paterson tanks (system 4 and universal), Jobo 1500 series, Yankee Clippers, and a Unicolor drum. (We also have stainless, but those are pretty easy to tell apart.)

I have separated the known Paterson reels and the known Yankee reels, and am looking for help identifying some oddballs.

The ones grouped in the set of 3 each have a solid core that is not able to be removed. The one with the black core seems to be adjustable, but I can't disassemble it without risking damage. The white core one is solid. The 120 reel looks like it has an extender, but it's the only one that does, I don't have any loose extenders. Are these Unicolor or perhaps a discontinued Jobo style?

The two attached to the same tube are I think a Jobo reel jammed onto a Paterson tube. I can detach the top of the top reel, but I can't move the other part of it at all. The Paterson reel below moves freely. Any tips for getting this unstuck? I've tried soap and hot water, a blade to loosen the seal, and twisting. Nothing seems to work.

Any assistance or tips would be very helpful!

Thanks!

Of the unidentified reels, do any fit on Paterson posts/cores?
If so, they may be like the AP/Samigon/Arista 3rd party reels designed to fit into the Paterson tanks.

No, the attached cores are much smaller, the opening is probably only as wide as a pencil. They also stand too tall to be used in a Paterson tank without the tube (bump into the funnel). I am leaning toward unicolor based on some ebay results, but not entirely certain.

Unicolor for the Unicolor film drum. The Unicolor film drum does use the light tight tube that reels such as Patterson are fitted over, The Unicolor film drum has a plunger end that is adjustable to the number of reels in use and a fixed cap that is light tight, it is the end that chemister is pour in and out of. There is no hallow tube that the reels need to be fitter over.

Thanks, that makes a lot of sense!
