Quick question for Nikor tank

Dustin McAmera said:

I have a tall tank with the straight divider in the lid, and a couple of smaller ones with the round centre hole. I can't swap the lids between tanks; they're slightly different diameters, and I think only one of mine is actually made by Nikor.
I can't say I prefer one over the other much for the lid on its own. The tall tank is oldest, and leaks a tiny bit round the lid, but I'm biased in its favour, because when I open that one I have four films to look at.
Pouring into the lid with the straight divider, I tilt the tank a little so the air-escape is higher. Neither design is a lightning-fast pour-in: for that, get a Paterson and live with those nasty sticky reels.

The lid on the left is earlier. Both work fine

I prefer the divided lids, the idea is that you pour into and out of the larger side and the tank vents on the smaller side of the divider.
When they were made the lids were matched to the tank, so they don't interchange well. Nowadays with tanks sourced from the used marketplace, all bets are off as to matched tanks and lids so use whatever combination fits best. Otherwise you'll get a lot of leaking, or else a lid that's stuck and difficult to remove. Some leaking is a "feature" of most stainless tanks though.
