On another list - range finder forum - also a nice place - one member sent 
his front element off his Summicron to ARAX in the Ukraine and had it 
pulished and coated for 30 USD ! he was vey happy with the result. ARAX - as 
far as I understand - rebuild KIEV cameras to meet vestern standards and 
recement and coat lenses - I have not yet heard negative of the company 
!?! -  anyone comment on that ??
There is a small scratch on my Daugters Xenar front element on her 1953 3,5 
75 automat and I would like either a new front element or a 
pulishing/coating - is it posible to change the front element on a Xenar or 
is it individually fitted to the camera ??
I do not mind paying for labour and good work but a simple CLA in Danmark 
will cost you 350-500 USD without spare parts - the postage of sending a box 
of cameras to the US were I understand many of the best camera doctors 
recide is about 150-200 USD two ways -
is anyone familiar with a workshop that can fix leicas/rolleis/hasselblads 
in Scandinavia/germany at reasonable prices ??
All the best

    Arax may be an alternative but I think I would want to know more about them 
before sending a lens or a part of a lens off to them. 
     Generally, the elements of lenses are matched. Its possible for a front 
cell from one Tessar type to work on another but there is generally some 
production variation.
      A single scratch won't hurt things much, certainly not as much as a 
plethora of very fine scratches. I would just leave the lens alone. 
       BTW, if you change the lens you might loose the match between it and the 
finder lens. This is critical in TLR's If you can get a good taking lens and 
good viewing lens from a junked camera you are home free.
