Folding bike (Burntwood WS7)

Old BSA Folder folding bike. In good overall condition (a very few small rust spots) but needs TLC. Unable to re-position saddle which drops down to base and cannot get it to stay up - just needs someone with stronger hands to adjust tightening bolt. Being old it's solidly built so not the lightest but it is a comfortable ride. I've invested in an electric folding bike so this no longer required. 16" wheels and Sturmey Archer 3 speed gears.
