Jobo 3063 drums, two different lids?

[Kodachrome25]

Hi, I just picked up a second Jobo 3063 drum and noticed the lid is different than my existing one. The new one is like the lids for my 3010 drums and the other 3063 has one that seems to have an extended light trap and sticks out more.

What I am wondering is if this just represents a design change or I have the wrong lid on the new one. The photos show the drums, label placement, lids....

Some lids have bayonet light trap attachments, others have a light trap soldered on.
Originally Expert drums were only print drums, and did not have anything in the middle like the sheet film expert drums have, so they used the beaker. Then all lids were changed over to the sheet film style.

The "extended light trap" will fit on any of the lids. It is meant for processing paper manually. The chemistry was held in the cup until the drum was moved to horizontal for processing. These are a bayonet fitting and can be replaced with the other trap for use with film.
