Dr Feickert Protractor


Hi 

I wonder if anyone can help.  I've just sold a Dr Feickert Mark II Projector on a well known auction site - it didn't have the allen key with it and the buyer is asking me what size key he needs to buy  - would anyone know what size key is needed for this ?   I've checked on the instruction manual and it's not listed. Many thanks.

I modified my MFSL Geo-Disc after seeing a Feikert.  I added a straight edge ruler for better alignment to the pivot point of the arm.  I always hated the guess-a-mation when lining up the arm pivot point with the G-Disc.
