Several months ago I posted the photo below. I was asking for help in identifying the model. My question was quickly answered.
Today my cousin and I were looking through old family documents. We found the registration receipts for this 1913 H-D 9E. My grandfather had registered this bike in 1915 and again in 1916 in Oklahoma (cost $2.25).
The engine or serial number on this bike was 7416.
Where would I began to look to track what happened to this particular motorcycle? I would be blown away if I found this motorcycle in a museum or private collection somewhere.
Thank you for any assistance you might be able to offer.
