And is it clearly denoted on the rods or frames whether it is an RZ85-3 or when it may have been manufactured as there is no documentation remaining with it?
It is normally printed in the "ladder"-piece, but it can fade away rather much. If you don't understand what the "ladder" is, then it is not a RZ85-3

In Sweden I have seen at least 10 old Pouchs for sale, and all except one has been RZ85-3. The other was some RZ85 variant with bottom piece of plywood (not ladder like) and also the most other parts in plywood. I searched some then, and got the impression that that version was a very bad variant.
