This photo reminds me of my grandfather. His idea of maintenance on the TT was once a year in the spring:
1. Emory the coil points.
2. Emory the plugs
3. Check the oil and add if needed. (Never waste good oil by draining it!)
4. Check tire air pressure.
Once these things were done he was good to go for another year. Just add gas and water as needed.
I've seen that photo before. There are two or three others in the group taken at the same time. The photos were taken outside a wrecking yard in the late 1930's. The wrecking yard owner is swapping Model T coils into the customer's car to find four that work.
Check out the "disc" wheels off the old boy's left elbow !
I didn't see those wheels. It's hard to look away from his hat.
Looks a lot like the "spare Michelin" I've been hunting for several years now !
I like the accessory horn mounted on the support rod I think everyone can find something in this photo they wish they had now
