I noticed your post on the Great Lakes website. I think you will find the Great Lakes to be a great airplane. (pun intended)
By way of introduction, my company, Great Lakes Aircraft sells and services Great Lakes from the 1970-80s. The inventory of Great Lakes may be found on our website, greatlakesaircraftcompany.com. You might want to look it over at your convenience.
We just acquired another Great Lakes that is not listed yet. It is an low time airframe and engine, undamaged, and being recovered. . . . .one of the nicest 'Lakes I have ever seen. Full details will be on the website later.
