I just purchased this NOS Sireno Searchlight, that is new in the box. Looks like it's about 1978 or so. If anyone is interested I can get my hands on two more for $150 each, let me know ASAP.
That's a pretty good price. I moved a couple of these in similar condition from a long closed upfitter cleaing out old inventory. I think I was able to move them for about $250 each.
