I haven't followed this thread too closely but have seen maybe a couple of hundred or so EY rifles in service in the past. Not in use I should add but from war reserve stocks being overhauled on a rotating basis. I have to say that of those, they were all Mk3 or 3/1 variants with serial numbers in the general run of numbers. We'd have certainly noted oddballs, such as any without the charger guide etc. And if our numbering range was (generally) within the G prefix range, we'd have certainly noticed that - as we did with the LB Mk3 Brens and VS Mk5 Stens.

That's only in UKicon Military service though and only my observations. I never saw a discharger cup in the Armourers shop but someone told me that they'd been overhauled/greased up in the A&G section (the Armament and General section as opposed to the SA&MG workshops!
