RE: Modified Hotspot
Those look exactly like MM gear. Even the Robart 630 that aren't blue look differnt than that. The sides give it away. Let me guess, haviing problems with bending the side walls? And the trunion seems a little soft.
I can post a pic later of a MM gear I have, I'll do so in a little bit.
FWIW, The MM gear almost look identical to 630's.
