Hi Perry,
Try Brent Mullins in college station Texas. 979-690-0203 He has all kinds of neat stuff. He even found me a complete spare C-4 Carb. Also try David Yamulla in Penn. 570-454-5674 he has a ton of Sherman releated parts. He also owns probably the worlds finest restored Sexton. Last but not least try Kevin Kronlund 715-635-9203 he also has a boat load of stuff. What kind of mags does you engine have, their are three possible types. I just sent several weeks ago a manual to Brent on how to rebuild the mags. My gal friday accidently sent the original TM and the copy I believe. He should have a copy. I also have a spare set of mags, I will have to look to see what make they are. Bosh or Bendix can't remember. The WWII Learning center in Hubbard Ohio has a cut up Sexton behind the place. Owners name is Henry Venetta, also a nice fellow. I have been looking for a complete spare engine and/or for my next project. Starman & Muys don't have any at this time. Starman does have a nice collection of engine parts. some are C1 not C4. I am about 1 hour North of Detroit. You can contact me direct off list at
