I know of three F type three wheelers within 70 miles from me. And ther is a Gent some 140 miles north of me that has three all definit years. Mostly not driven I suspect only looked at in the garages and at shows.
I have seven old Moto Guzzi singles 1937 and up that I treat the same way. Just to hard to find spares. So I ride them very sparingly.
I am glad to hear so many made it to the USA and your area. Are you in the vicinity of Washington State?
Yes, I'm in Vancouver, WA just over the river from Portland, OR. I joined the NW Morgan Car Club and have been tracking M3Ws down. I found what they call the Southern Pod group to be supper nice people and a blast to be around.
