The picture looks like a deep spring, a bit different than yours? Anyway, the original ad looks much like the deep spring Messinger I have if you are trying to find what one looks like.
Check it out. Still waiting on the handlebar, stem and crank
Fender braces. Simple washer welded to the steel. Will drill two little holes to install some rivets just to get the look of the original. These came out so solid that the fenders do not wiggle!
I'm having second thoughts about using the original headbadge. I'm thinking a custom made harley davidson badge. Maybe a two piece badge. Maybe one piece brass the other one aluminum or maybe both parts brass. What you think? If I do change it I will also have to change the frame stencils.
Still waiting on handlebars, stem and crank. I also forgot to mentioned that I will be using schwinn fenders. Got some buffalo leather today on the mail and I think I'm going to build a custom tank out of that leather. Currently prepping the frame and fenders for some rattle can paint job!
