That Aqua cabinet was first available beginning in late 1966,all the way through the 1970's.
They were available in three designs within those years..
Wall mount Horizontal.
Wall mount Vertical.
Floor foot mount vertical.I've got one of these.
I have a dealer merchandising catalog showing the sizes and differences from that time period.The order form is dated 1968.
That brochure rack looks to be 1972.I'm not positive on that but just looks like one I have in a 1972 merchandising catalog.Is it solid wood or particle board with a dark wood veneer?
Good stuff!
