Thanks for the information. Yes, there is a capital letter "M" in a circle on at least one of them.
I will try to figure out how to post some photos of them along with some of the others. I love this old stuff and am totally new to the Model 'A' thing since I talked my youngest son (45 yrs old) into selling me his unfinished 1930 Model A Coupe. I am in the latter stages of finishing the car.
For fun, I think I am going to make some magnetic door decals that will look like sheriff's car decals. That will be great for a one car parade in these little rural towns around here. That's easy for a sign painter like me...
Thanks again.....
