An interested collector can get stuck in there for awhile...
You are correct on the purple one. It is an AGEE. I believe it is a AGEE 30 or a CD-422 I believe.
The green one to the left of it I believe is a Brookfield. I picked it up to look at it but I forget what it said. I will have to ask him next time I talk to him.
