I found another obscure Rondinax clone and I thought you might be interested to have a look at it.
This one was made in France by Inox (renamed Prestinox in the early 60’s), a French manufacturer who was specialized in photographic equipment & slide projectors.
It was originally sold under the name Rondinox and, at some point, it was renamed Laborex, as stated on the instruction manual of the latter. (I attach a PDF of the manual)
The photographs were found on eBay France.
