OK, kind of funny but not funny. I had what I call a stroke moment with these magazines. I call it that because I watched my Dad do these things after he had a stroke and I have one every once in a while after mine.
I looked at the base and figured the logical seeming way to get it off and slid it that way. It was very tight and wouldn't come off. So I look at it closer and yes, this is the only way it can come off
It wasn't. I figured it out today. Push it the other way.
The parts all seemed to match the exteriors so they weren't mixed up. There are basically the same but the fourth seems more cheaply made The lifter is in two parts and appears cast. I'll get some photos up maybe tomorrow once I get them organized. Three are marked MA which I saw somewhere means LithgowAustrailia, One is marked MA '42 the other two MA with a smaller font and it's one of these that has the weird lifter. The fourth is A in a circle.
