Substantially sized 13A plug made from flexible white plastic.
White moulded plastic plug. The top has 'BRITISH MADE FUSED' moulded into the plastic lid. Line and neutral pins are sleeved.
The plastic is a slightly flexible type and has yellowed somewhat - although most of the yellow colour is due to greasy dirt on the surface.
Internally, the flex grip is two pieces of black plastic, no screws required. A 13A fuse is fitted.
Each terminal has the wire colour moulded into the plastic - Green/Yellow, Blue and Brown.
The green colour on the fuse is corrosion, and the entire insides are coated with grease - probably from a kitchen.
The base is marked BS1363A, 13 AMP, 250V. All three pins are labelled (E, L, N) and the earth pin also has the earth symbol.
The 87 is possibly the production year, and the 'clock' style design above is probably the month as there are 12 positions.
