First up: Screens of Schooner Bay. I have two, however, I am having great difficulty locating one of them. They were free to me, I don't use them, thus they (assuming I find the other one) are free to a good home if you'll cover the cost of shipping.
Second, I have a "Horse Shoe Buoy Pony" with bracket. The rail mount is missing a couple of screws, but shouldn't be a problem. Its a bit bulky and may cost a bit on shipping. $125 new and the bracket is another $33. This one has been in the dock box for years. I don't know how many, I have a lifesling now. Make me an offer.

Next I have a Garmin GPS 128 with external antenna (required), power cord and manual. Works fine, I took it out to install a Garmin 441S. $100 OBO. The antenna has never been installed (I have a second on mounted on the rail).
Also a Ritchie B-51 lighted, bracket mount compass. $50.

Finally, I have a Davis Mark 25 Sextant (pic pending). Excellant condition. $150.00 It on the boat. I'll get a pic sometime today.
Send me a PM for contact information.
Fair Winds & Happy New Year
