You could contact True Lens Service in the UK or P&S Technik in Germany or GL Optics in China or possibly Duclos in the states.
Many C mount lenses aren't worth the effort IMHO. What lenses did you have in mind?

I was thinking of an Angenieux 15-150 for an Aaton LTR 54 with an Aaton mount.

Ideas about re mounting a C mount on a 15-150 have come up before...
Jean-Louis is a current member and may have some insights. So may Dom now that he knows what lens you are thinking of.
If you were searching online, the term "re-house" would take you down a different rabbit hole.

Those old Angenieux zooms often came in a variety of mounts, including C mount, Arri Standard, Arri Bayonet, Eclair CA and others. The 15-150 seems to mostly come in C mount but I'm sure I've seen a B mount version. Definitely capable of being remounted, but it could be expensive, since it would probably be a custom job these days.
Someone was selling a PL mounted version here last year:
As Greg said, lens re-housing is a different question, usually involving a full exchange of the lens mechanics. You just need the mount changed, which is much simpler.

TLS as mentioned are the gold standard. They make wonderful conversions. But it takes years to get it done with them and it costs a fortune, so not for those who are in a hurry or light of wallet. Also, for one-off lenses that have not been done before, the engineering costs here in the West are just not competitive. You'll pay way much more for a conversion that for buying a brand new lens, in many cases. But, if you want to go down that route, then your best option is Nan at GL Optics in China. They'll convert anything and do one-offs. I just had my set of vintage 60's Lomo sphericals (don't think a set has been converted before) done by GL Optics and they did a great job on them. Had to send the 28mm back to get it re-engineered as it vignetted a bit, but other than that very happy with the workmanship. Just to give you an idea, it's about $2.5-$3K/lens to convert an old set in China. You can triple that cost at least if you want to do it here in the West.
There's a new player that converts here in Los Angeles called Zero Optik. Their conversions look great, but not sure of the cost.

how is the lomo conversion? I have a couple of jammed up lomo superspeed lens, they are basket cases, can they rehouse, if the elements are ok, bu the aperture or focus is jammed?

Haven't really shot with them yet, just tested them. But I love the lenses - they have a look that reminds me of the old 60's Schneider Xenons, which I love.
Yes, they would be able to fix that and rehouse it. Iris's are pretty easy to free up.

Thank you all for all the very valuable information. I guess I should have said "re-mounting" instead of "re-housing."

I just happened across your post looking for something else.....
Why don't you contact Paul Hillman here at Visual Products. He's done many, MANY of those through the years and we had parts made specifically for those lenses so should have something in the drawer to sort you out.
Our number here is (440) 647-4999
