My 1953 Chevy Truck came with an autolite turn signal. I am guessing this was added in the 60's or 70's. I would like to find a 6 volt turn signal that would have been installed by the dealer in 1953. I have done a lot of searching on the internet but I haven't been able to find anything definitive on the exact type/model that would have been installed. Can someone post a photo of an original dealer installed turn signal from 1953?

Thanks!
