Found a one owner 1917 Mack AB near Baltimore MD. Was stored in a house garage since 1988. Prior to that it was stored in a barn on the eastern side of Baltimore since the 1940's. Truck is in excellent condition but will need some TLC
More parts printed:
If there's interest, I can custom print emblems
The blue parts are plastic (PLA) and as-printed without any cleaning.
I spent about 10 minutes cleaning the blue parts and then sprayed them with primer.
Another 20 minutes detailing can make a big difference
Plastic can be chrome plated, but it requires a lot of prep work as every flaw will show
The Horn Button
Still tweaking the pieces
Three pieces Super-glued together
Will need detailing to look smooth like the original
I'm not sure the hardware for my horn button is correct - the button is too far above the steering wheel
Not sure how the plastic will hold up.
It wouldn't pass today's requirements of:
500lb Gorilla tugging on the handle
But, they're better than what's on my truck
If there's interest, I could make a mold and cast them in brass or bronze (or alum or...)
