After doing some digging, I found that this is a Fowler 16263 'Talisman' belonging to the Pickfords removal company delivering an M.G. cylinder to St. Anne's Board Mills in Bristol in 1938.
Whoever wants to info dump on this thing, now is your time to shine. There are cars decades older than this thing, so I'm really interested to know what the deal is with it. But I know if I look it up I'll go down a several hour rabbit hole and not sleep again tonight.
