rookie, have you asked Google what it can find for either lens? I just did.
It returned a moderate number of offers to sell, a few questions about what the lenses are good for and no reports from happy users. There's no evidence that the cells, if the lenses are made with cells, will fit standard shutters. Re made with cells, we're used to lenses that consist of two cells, front and rear, that screw into a barrel or a shutter. Not all fixed aperture lenses are made this way. Some have stepped tubes with the bits of glass glued in or held in place by retaining rings. I have one such (retaining rings).
I've looked at the image you gave a link to. Not that good.
However, its your time, your money and your joy of tinkering. Don't pay much, play and enjoy yourself.
If you want an enlarging lens with variable aperture, buy one. It will be less expensive than getting one of these gems and paying to have it adapted if it can be adapted. To give you an idea of potential costs, in 2002 I had the late Steve Grimes extract 38/4.5 Biogon cells from an AGI shutter and make adapters to remount them in a Copal #0. He charged $300 for that work. I'm sure that prices have risen since then.
