A Woolworths product.
Winfield was a brand used by Woolworths, and this item still has the original price label on it - 6p.
Three values of fuse wire, 5A, 15A and 30A.
This is probably from the 1970s.
The back is plain, but has the name U Jones written on it.
Jones is a very common surname.
First names beginning with U are not.
Another very similar example, this one has square corners. The price label has faded to the extent that the price cannot be read.
Most of the fusewire is missing.
A more recent version, price 11p. This is in virtually new condition, none of the wire has been used.
It is likely that these '480' cards were actually made by Volex, as the reference number and card design are the same as the Volex equivalent.
Much older, this blue card contains only two types of wire - 5 Amp and 15 Amp.
5 Amp for lights and small plug circuits, 15 Amp for large plug circuits. This probably refers to circuits supplying BS546 socket outlets, which were available in 2A, 5A and 15A types.
Switch off at the mains before mending fuse.
Use the correct type of wire. See Above
Made in England. Ref 490
This partially complete example is probably another Volex item with Winfied branding.
Originally containing three types of fuse wire (5/15/30) and two types of BS1362 cartridge fuses.
The lower half of the card has been torn off, and the back has signs of water damage.
