Check out Carsten's posts (user: carstenw). He has a link at the bottom which shows the codes for the lenses including the Tri-Elmar.
Thanks for your help Mark. I used a small spherical router bit and flexible drive, therefore raised edges on the grooves were not a problem. I checked for flatness after 'milling' and if there had have been any raised edges I would have levelled using a needle file.
