FS USA - Hewland Gearbox Literature
I found a few more things that John Horsman gave me a few years ago. There are original Maintenance and Overhaul Manuals for a Hewland LG500 & 600, a DG300 Mark 2, and a Mark 8-9. In addition there are blueprint drawings of Hewland- related installations. Offers?
