A Clubman like this (but in white...) was my first bass. The original tuners were much smaller (probably guitar tuners that Vox used for everything at the time...). The output jack on these is not a standard 1/4" jack socket, so a special lead is needed to plug it in to an amp. A very short scale, so well-fitting strings are not so easy to come by.
As for value: we don't do valuations on this Forum, but be aware that, unless it interests a Collector, they are not much in demand, and were extremely inexpensive when new (mine cost £20, new, late '60s...). Mostly curiosity value, really, more than as a musical instrument; they're not very good, as basses. Only worth working on for sentimental or novelty value, or as a wall ornament.
Hope this helps.
