Sadly, Thorlabs only has M62 X 0.75 thread adapters
BUT By GOOGLING "M62 X 1 adapter" I found one that is M62 X 1 (female) to T2 (male). Unfortunately the adapter is long, so it would only be useful most likely for close-ups unless your lenses have a very long registration distance.
M62x1 female to T2 male thread adapter
In any case do some more GOOGLE search, or try EBAY. Some Chinese company might offer just the adapter you need.

Here I am again, with things getting complicated.
1) on EBAY search for M62X1 adapter. From Russia there is a very short adapter that is M62X1 female to M65X1 male
2) Then search for M65X1 adapter and you will find many, including M65X1 (female) to Pentax 6X7(!). There are also M65X1 adapters to other medium format cameras.
3) THEN...............
It looks as though M65X1 was used for a variety of projection lenses, hence the availability of adapters to mount such lenses on medium format camer.
Keep searching. Somewhere there may be an M62X1 or M65X1 to M42 adapter.
BINGO! Search EBAY and get two adapters: 1) M62X1(F) to M65X1(M) then there is an M65X1(F) to M42(M). the first adapter adds only 4mm, the second appears to add less. Then all you need is a K to M42 adapter. CAN BE DONE, but you may not get infinity focus depending on the registration distance of those unusual lenses.
