I'll have to check through my old mags; that one would appear to be 1954/5?
snide and sharke speciallsed in selling cheap oddities like Pannonia; TWN; Motobecane scooters, weird mopeds of all kinds and Small Italian stuff,
I bought a good part of their stock when they closed down. Too long a tale to relate here, but I can assure you the name snide and sharke was appropriate right till the end. Staff had more fiddles than an orchestra. I bought a room full of mags and dynamos, there was only half a room full when I turned up to collect them
There was some right crap in Geo Clarkes Brixton Hill shop, even the walls were oily.
