Britbike forum Forums British Motorcycle specific Brands Norton bulletin board TEX Viewmaster mirrors.

The 'postie just dropped these off, I am fairly sure these are TEX Viewmasters ? which will go on my Mk2a,I have only seen a few used pairs for sale over the years and never NOS, can someone confirm these, They look like the ones in the Norton Commando brochures.
I have no reason to doubt the seller but just to be sure before leaving eBay feedback.

They're the correct shape and style.

The ones I have, all have "MADE IN ENGLAND TEX VIEWMASTER PAT" (followed by 6 mostly unreadable sets of patent numbers). The mirror backs and clamps are stainless steel and the nuts aren't magnetic.

Thanks Les :bigt
I had to get my reading glasses out for that one, these have the writing as you describe and would not have seen it without your direction.
NOS Viewmasters they are and in fine condition for their age. (perhaps 40 years)
