Sourcing powerful magnifying glass

Many years ago (20+) I used to live next to a (industrial) lens factory,
and our neighbour who used to work there brought me a damaged magnifying
glass. See a couple of photos he

It is much more powerful than the average ones that you can easily get,
and I have used it ever since.

I now want another similar one, but looking online doesn't seem to bring
up anything.

Any pointers will be much appreciated.

TIA.

PS: the factory no longer exist, and is more that 5000 miles away anyway…

Go look on ebay for Gnome Beta II enlarger. The condensers inside them
looked exactly like that and were quite big
