Fine metallic particles in the sump will cause problems if not quickly captured, hence the use of a magnetic sump plug makes sound common sense.
“J&E Engineering Services” has manufactured two batches of these units, one for the Daimler V8 saloon, and one for the SP250 and the Majestic Major. 
The Majestic Major sump plugs were originally made of brass and over the decades will have been subject to some significant wear and tear. 
 
All sump plugs produced by “J&E” utilise powerful rare earth magnets to attract the smallest of ferrous particles suspended within the engine oil. The unique design does NOT rely on the magnet alone or adhesive to secure the magnet to the plug, but rather a rivet through the centre which prevents magnet detachment whilst in service or being cleaned; hence a far superior design. All sump plugs come complete with both a bonded (Dowty) seal and a copper sealing washer for your preferred option.
