## Product's reviews:
- Boston gear order - MRO had the items that I needed. I ordered them and they were shipped faster than I expected. It was a pleasant experience all around.
- Gear box oil - This has been very hard to find. It’s the oil spec’ed for my 1950s Rockwell wedge bed planer gear box. I haven’t found it anyplace else.
- New lead screw gear. - Used this gear on a new lead screw l made for my old 1919 LeBlond belt drive lathe. It worked great for my application.
- Quality - very high quality. using these gears in a model 9 cylinder radial engine with a 1"
bore. about 8 h.p. , for oil pump a scavenge pump timing gears and distributor . very good quality gears.
