This one I think will be one of the first to do. Hobbs Tandem - track bike re- enamelled by Roberts and modified to take derailleur.
Some wheels, a couple of brooks saddles or equivalent, some period bars, pedals - I wonder if the 4x B8 ones in the box of bits are period ? And maybe that’s all it will take to get it on the road.
That 58 Chain ring might need changing for my little legs 😂
