I dig 'em, obviously...see picture to left. That's my '41 Indian model 741 (military). I "civilianized" it. Also had a rare '44 Civilian Chief. Called an "Essential Civilian Use" model. Had to have permission from the government and an essential war time job to get a certificate that allowed you to buy one.
Interesting that Indian factory referred to their bikes as "Motocycles" and a lot of the dealers (based on the above photos) went with "Motorcycles". Guess if it's your shop you can put what you want on the sign.
Great riding bikes, loved the Chief especially. Low center of gravity and very torquey engine so you didn't have to shift constantly going up hills. I lived in Albuquerque when I owned that one so that was important.
