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.

Just buy a complete set from Harbor Freight.  They are inexpensive and your customer will find the one that fits.  BTW, I doubt one could even purchase just a single Allen key.
