Back in the 60s, one of the import companies sold a 22 semi
auto pistol, that could be hand with a carbine that used the
action of the pistol for conversion. The pistol looks like a Unique
m-52. Does anyone recall the name or importer that it was sold
under? I have looked through lot of books and can't find it. I could have been earlier than I remember.

Unique Model L.

This link should be allowable - the auction has been closed since 2012.

Thanks Alpo, that's what I was looking for.

Interesting combo. I noticed they reported that UPS broke the stock. What a coincidence, they broke the stock on my Ruger .44 carbine also.
Same driver maybe?

How about a new model using a glock or m&p

MechTech - Home I think a couple other companies make them for glocks and 1911s too, not sure about the M&P.
