New lenses - Zeiss ! But what do I do with them ?

I have just aquired (but not received) the following batch of lenses - yes, buying in batches is the way to go -

Meyer Telemegor (aluminum) 400/5.5
Zeiss Biotar 75/1.5
Zeiss Triotar 135/4
Zeiss Tessar 40/4.5
Zeiss Tessar 50/3.5
Ludwig Meritar 50/2.9

All Exakta mount, all allegedly in good condition, but we'll see. All seem to be of the same vintage. The Biotar is I believe this version -

Odds are thats the most valuable item here.

What do I do with them ?

I intend to keep the Telemegor and convert it to M42/PK, I think thats not too hard.

The rest I may resell if I can't make them work on my Pentax. I have Exaktas, but I can't justify holding these possibly expensive lenses - well, not the Ludwig - given that I don't expect to use the Exaktas much.

Any suggestions as to value, quality and ways to get them to work on Pentax K are appreciated.

With a Biotar 1.5/75 in your hands, you should definitely try to get it to your cam...
If nothing works, go and get an EXA cam you can use these lenses with.

75mm 1.5 is a jackpot ! You never seen sharper lens at wide open,

40mm f4.5 high quality lens too,

I use exakta lenses on Olympus 4/3 perfectly. I have no idea how you can use on pentax. 75mm f1.5 price can be reach 300-500 USD perhaps better to sell it and buy pentax fit lenses.
