J0490 is listed in the factory records as a black four-seater tourer with green upholstery. No mention of a 'Special Sports' body. The body looks like a J1 body that has been shortened and a J2 fuel tank fitted along with J2 wings all round. It was apparently owned by a J. Cheeseman from Oct 1934
If it is Chessman was he from Tunbridge Wells as I seem to recall a gent of that name being involved with Kimber during earlier days? Haven't time now to trawl through O to A just now.
John is correct except for his spelling. CRB Chiesman was a frequent driver for the works MGs in the pre MMM years. With such a distinctive surname i wondered if J. Chiesman might be related.
My Cheesman must have been predictive spelling as I had typed Chiesmsn and I originally had the i and e transposed.
As Kevin says he was very active in pre MMM days and I say Tunbridge Wells as I believe his family owned a big department store there, which was still there when I lived there in the early 70's.
