This vintage surplus Canadian Forces "illuminator" that I found at an estate sale. This item was made by Swiss manufacturer Albiswerk Zurich AG. This item stands approx. 30"high x 20" wide. I don't know if its operable because you need a power supply to plug into it. This item appears to be a portable field unit as it has shoulder straps & back brace for transporting it. I tried searching the internet but could not find any info on this unit, I believe it is 1950's / 60's vintage. Unit comes with canvas cover.Great conversation piece!!! $125.00
