was the machine originally red with with cream/off white wheels because the only model fitted with a Kohler K91T fitted was the last TS model made about 1970/1972 engine parts are available from Meetens at Preston who do an excellent mail order service as regards tyres there is a firm called China Parts in county Durham there is also Villiers Parts but George can be a bit troublesome at times so I personally use him but many have had good service
