Goggles Identification, Please.

[Viscount]

Any suggestions please as to the identification of these goggles? There are no markings as far as I can make out. There is some elasticity to the strap.

Many thanks
Bob.

Many thanks. Very much appreciated. I paid £6 for them recently which I suspect was a good price in the circumstances.

Thanks again,
Bob.

6 Pounds? You stole those! Good job

Would this pair be the same? If so, my luck is in. Although the strap is probably a replacement.
