M8162, 12AT7WA,  Mullard, Wrinkle Glass,  CV4024, ECC81, Whyteleafe A, Feb 1963 Production, RARE

Now this truly is a RARE device, hailing from the Whyteleafe A factory, with a February 1963 production etched code of the 652 variant, this beautiful device shows full emission but sadly, smudged print.  The print shows the military cartouche on the front, but the high grade commercial notation of M8162 on the obverse.  

A rare device for the connoissseur indeed.
