Ferg it was usually a piece of thin black manilla card with the half moon cut into it. You can buy it from a craft shop nowadays. Ron

Hello Roy,

So it is put inside the headlamp between the reflector and the glass right?

Beautiful motorbike indeed.

Thanks in advance,

Regards,

Sylvain Breffy.

Hi Sylvain,

I have an original of that model black out mask and can send you photos and measurements of of it if you want.

Hello Henk,

Thanks for your reply. Yes if you can that's with pleasure to see one more of your beautiful parts.
I have measurements from your DVD, and I made my own, but didn't know if I must put it inside of the headlamp or outside? On some pictures it seems to be outside of the headlamp, just put on the glass, so just ask to be sure ;-)

Hi Henk,

I wouldn't mind the drawing if that's OK? I couldn't find that on the BSA Dvd.

The lower half of the refelector should be painted with matt black paint as well, but that's perhaps taking things a little too far !

The 1938 'Mechanized Movement by Road' training pamphlet actually referred to an opaque cardboard mask and it seems from photographs as if some early war vehicles actually had masks made of the brown envelope paper that we would normally regard as 'manila' At some point this became the thick black card like Henk's NOS mask.

Cheepest option is to paint the inside of the glass blue as per BEF instructions but there is the risk of a pull for impersonating the rozzers !

Hi Dave,

I just send you the info on the black out masks. The one with the measurements is the original one I have myself. For the early BSA's there was also a small black out mask for the MT110 tail-light, I have send you these photos also.

You can of course also make one from an old Shell oil can.

Hi Henk,

Thanks for that, your original one is very nice Not too sure about the tail light,
that's a very tiny hole!!

That's one clever way of recyclying an old can, I have seen the photo before, but never noticed the can.

That tiny hole is there just for the number plate illumination so still lots of tail light left.
