Around 1985. I know the latest "B" Blackburn codes I ever saw were 1984 or so. As for their other plants, I know they rolled out those (IMHO) JUNK '80s vintage milspec ECC83/CV4004 boxplates coded KQ/QDD (or whatever code-- I only like the 1960s and 1970s CV4004s-- I'm not sure how Mullard screwed that tube up SO BADLY in the 1980s); the CV4004s I bought and sh**canned had date codes of 1984 and 1985, at the Mitcham plant, though, not Blackburn. I think Mullard was DONE by 1986; I ordered what I thought were going to be XF4 EL34s by Mulllard Blackburn in late 1986 and they turned out to be East German RFTs with Mullard "foxface" logos! Hope this helps; others are more into such details-- they could give you the time of day when the last worker left! :00)
