Hi. I've got a few "antique" fuses from British cars. They might be 30
or 40 years old. They are very like type 3AG glass cartridge fuses,
about 6mm dia., but about 2mm shorter at 30mm.  They have coloured paper
inside them. The ends are flat, not rounded. I say "antique, but they
seem to still be used. Folks might just call them car glass fuses.

The ones I have are:

2A blue; 10A orange; 15A cream.

Do these old fuses auto have an official type reference? I cannot see
any reference on the WWW. Not even at:
