Singer Challenge, fully nickled

This 53 inch Singer is fully nickeled. Most firms offered this as an option on all models except the basic versions.
With its serial number 41375 it was built around 1886. It features the later type of detachable handlebars, and serial number on right side of the neck. It is a marvellous and original bike with beautiful patina. I am not sure about the saddle, it may be an aftermarket saddle. But it sure is old and it fits the bike very well.
