Depending how local to portsmouth you are, I bought from 'Sabre Sales' Army Surplus, a modern AFV Crewmans Overall, which has a sort of sewn-in 'rescue harness' in it, -£25, in new, un-issued condition, they are similar colour to lightweights,but of a thicker material than normal overalls and very close in construction to the 'tankie-suits' mentioned in an earlier post, also a darn sight easier to get hold of, unless you are about 5' tall, -I'm 6' 1", and I've been looking for a genuine '50's - '60's 'tankie suit, for about 5 years!--can't find any! The modern ones are very, very comfortable to wear, either with shorts and 'T' shirt under for summer use, or long sleeves and lightweights/jeans etc under for cold/winter days.... i wear mine when driving my Saracen around(I tend to warm up quickly, since I sit astride the gearbox, and to the rear of the engine).... well worth the money! PM me if you need any more details.... oh, they also do D.P.M. camouflage ones too!
