Hey TNT,
Thanks for posting those tool pictures. I have a DOE identical in form as your Royal S-14 only mine is marked:
9/64 ROYAL S-30 7/32
I never made the Royal typewriter connection but I have now frittered away almost 2 hours wandering the internet getting knowed up on typewriter mechanicing. Ah well, it's midnight, -10F outside and I wasn't going to get anything accomplished anyhow.
Happy New Year! Steve
