Hi! And what do I have here?

[JPons]

Quick intro, I had a small camera repair business with a partner that passed away a few months ago and I'm in the process of selling all the cameras and parts we accumulated over the past 36 years or so. I've come across some rare items that I had forgotten we had. Some stuff i don't remember even buying! And that's what brings me here. Does anyone recognize this Rollei intervalometer? I've spent hours searching the internet for any information. I have the owners manual and know how it works, but I'm trying to find a fair price. The rest of the Rollei equipment is long gone. This is the last of it. Any help would be much appreciated.
Thanks!
