You may have got the email: the ETF is reopening Jul-11
I wonder if Steve has any 16" round for my '51 Zenith - these used a metal-funnel tube that was bad news, like all metal/glass tubes. I note however that RCA had an all-glass 16" round slightly later, have thought of poaching the one from my RCA, but it's a cool TV also You can see the Zenith metal/glass tube in front of the RCA below:

Well you're not that far from the ETF, easy 1 day drive I'd guess.
There are LOTS of 16" roundies on the CRT list. There's bound to be one there for you.
Surprised to see the ETF re-opening in July. The Covid situation in the US looks scary from here. Maybe where you are up north it's not so bad?
In VIC they had relaxed the social distancing regime a little, there was a Black LIves Matter march and 15(?) people tested positive. VIC state govt. has quickly reversed their position.
In NSW now, if one person tests positive it makes headline news and the curve has taken a nosedive to close to zero. Might this have something to do with the relative intelligence of ScoMo vs Trump?

Okay, just checked his list, very impressive! (I'm not an expert on early television, just amass/hoard many genres of collectables)
So I look inside Zenith cabinet and tube layout sticker says "16AP4 or 19AP4 picture tube" (must assume the 19 is another larger screen model)
Looking at RCA tube manual from 1965, it gives 16AP4, 19AP4 & 16GP4 as "metal envelope round" with slightly different deflection angles.
Manual further gives 16LP4, 16DP4 & 16WP4 as 'all-glass round' - interesting, as museum has a DP & WP (not sure what my early 50s RCA 16" has as I'd have to move things to check it, but remember it had checked good, though storage environment has wide seasonal temp swing - not good if it's a hybrid glass/metal tube.)

You get more and quicker temp swing due to self-heating in the TV, I suspect. There is a good chance your tube is still OK.
The different versions of these tubes mainly reflect aluminised or not and ES vs mag focus. All can be used, an aluminised tube with ES focus is preferred as it will be brighter, generally not need an ion trap and will not need the focus magnet / coil.

He's getting back to me with carton dimensions. What with some "syndicate" members wanting old tellys as well, it looks like we'll fill a container.
It's not too late to add to the order, but I wouldn't leave it much longer.

One word - Covid. Victoria lockdown prevented the original plan.
Shipping costs have increased 4 or 5 times the original quote.
I'm asking a friend who regularly ships from the US what sort of deal he can get.
