After digging deeper it seems you are correct with the 1953 assessment. The thing that threw me off was the small horn tank button. I thought the button was larger on Super Deluxes from this era. A good friend of mine and his dad "restored" it and I took it in on trade. The paint is really nice, but obviously not faithful to the original paint scheme. Chainguard is missing "Super Deluxe" transfers as well. I had a good friend that does electronic and tube amp repair re-do the horn and lighting and they both work. Overall the bike is pretty stunning in person and rides great. I am a restorer/refurbisher/conservator of classic racing bicycles but this one is a little out of my wheelhouse in terms of type, value and correctness. Any ideas of value? I'd like for it to go to an appreciative home first and foremost but want to feel confident about what isn't correct before listing for sale. Thanks again for any info, Mike
