Interesting No32 on 'that auction site'.....!

[PrinzEugen]

As I own a MkII scope refurbished by the seller to a similar standard I'm sure the one linked to by Roger above is the business.

I think the title of this one though, on the other hand, is somewhat misleading:

Lee Enfield No4T Sniper Kit Scope Cheek Rest King Swivel No32 Scope Base Pads | eBay

"Lee Enfield No4T Sniper Kit Scope Cheek Rest King Swivel No32 Scope & Base Pads"

On reading the title you might think you were getting the whole kit. The description does say it's a weaver scope, but all the same...

And while I'm at it I think this alleged 4t butt is a bit 'iffy':

WW2 LEE ENFIELD No4 (T) SNIPER WOODEN BUTT ORIGINAL GENUINE 303 | eBay

S51 doesn't look right (well, as much as you can see it..., and no apparent other markings on the underside)
