Asking for monetary value of devices

I want to know the value of some devices in my collection, if you can’t estimate, you could tell me what you’d pay for it. Not sure if I want to sell it if it isn’t worth money. I didn’t want to put this in Flea Market because it isn’t for sale (yet).


(Note: Wheelock MT not included)
I have a Wheelock HSPW-24-HFR 110cd strobe retrofit plate, with box. The box may have minor cosmetic damage. The device did not come with documentation. It seems to be compatible with Wheelock sync protocol, but I can’t find documents online that would prove this. The device is in great condition, it was purchased new-in-box. No scratches or anything.

I’m no expert on how much money you’ll get for that strobe plate, but with it being so uncommon and fairly unique, you could probably get 30 or 40 dollars for it.
