W.A.T.S. Co. Ltd. was based at 199 Ealing Road, Wembley, Middlesex, & was I assume one of the smaller tuning companies that climbed onto the tuning bandwaggon in the late 1950's, I have no information on them apart from some adverts that started in late 1958 with a small ad titled Morris Minor Conversions (now there is a coincidence I wasn't aware of when I set up this website) in Motorsport.
They were offering a Brake Master cylinder conversion that vastly improved braking power, this is not a product I have ever heard about, and they were also producing brackets for the rear suspension to cure axle tramp & also a front anti roll bar.
More ad's appeared during 1959 expanding their range to include other BMC cars, they also announced a 120m.p.h. Speedometer head (not seen one of those) and also a rev counter kit that could either be crankshaft or dynamo driven.
They also produced an illustrated catalogue, if anyone has a copy I would really be interested, especially as they were based not that far from where I grew up.
