Thanks to TOPAZ owner "Lee from Canada' for providing pictures and information on this rare model.
His comments are as follows:
"There are two designs slightly different than one another. The earlier design (attached picture) includes a small forward hatch, plus a 3-stay rigging. The Sailboatdata page (originally) lists these boats' manufacture starting in 1970. However, the article I attached shows they have been around since at least 1965. The Sailboatdata Topaz picture is the later design and includes a larger forward hatch area, a top-load lazarette, and a 6-stay rigging."
