- UK manufactured coil valve springs to fit 16H, Model 1 and Big 4 Sidevalve engines of the pre-war and WD type. Pattern taken from 1937 sidevalve engine. Price is per pair.
As can be seen from the photos, these springs are to fit the pre-48 type 16H engine, produced through the 1930's and also fitted to WD 16H engines through WWII. They may also fit the post 48 16H engine . . . but as I no longer have one of these engines I cannot confirm this (the valve spring in that engine is shown in catalog as being A2/144). If someone has a valve spring for this engine that can confirm length and inner bore diameter, I would be very grateful if they could email us to confirm - firstname.lastname@example.org, as I can then update this listing or look to have that spring manufactured as well
