Cheers guys, I'll check out the rear mech when I get chance for a date stamp. Yeah it needs some drops, will have a look for some big ones, I wonder about the current ones as having done some digging about the history of this bike I think it's been in the state it is in for some considerable time (maybe stuck at back of a garage for a couple of decades), I've looked briefly at the bars and they seem to have logos stamped on the underside of the bar and some zig zag scratches on top, my wonder is maybe the original owner has flipped the original racing bars cut the drops off and moved the brakes but I could be talking twaddle, also might put a better saddle on if I can find something.
