## Product's reviews:
- Good seller - Catalogue item, good price, fast delivery = good seller
- 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.
- Exactly what i needed - Item was exactly what I needed and a perfect fit for my project. Extremely happy.
- Fast shipping - I ordered this part hoping it would arrive within 2 weeks because I had an emergency situation with an employee waiting to repair a piece of equipment at a customer’s location. The part actually arrived halfway across the country in 5 days including the weekend. MRO processed, packaged and shipped it with incredible speed. Thanks again!
