Not all that long ago, I could not get a rise out of anyone when offering a bicycle such as the one presented by the OP. However, that is changing. These days, the antiques seem to be gaining in popularity and fetching better dollars all the time.
That said, I really have no idea of the bicycle's present value. I would not pay more than fifty dollars for such a piece but that is just me.
I am a period and price point correct kinda guy. With that in mind, I do
my own paint jobs and I use a paint brush to do my work. Laugh, if you will, but
this is the sort of thing that you can achieve, using the simplest of tools, coupled with sound application process...
