The second dish is confirmed as a 1.0m. I slapped together the worst adapter possible to mount it and try aiming it. Receiver sees the LNB, but wasn't able to lock anything. I assume it's the bad hack job of adapting a mount for a 3" OD pole to a 1 5/8" pole that's not plumb...
A little PB and the elevation fine adjustment works perfectly. The plastic covering the feedhorn opening was essentially gone, so I broke off one small piece that was covered in desert sand/dust. Also removed the beginnings of a bee's nest (of course).
So here's what you get:
Dish 1: 1m former Muzak dish, NPRM, original feedhorn, single-polarity LNB
Dish 2: 1m Channel Master / Primestar dish with original feedhorn, original LNB with H and V outputs, seems to fit 3" OD pole
As stated in the original post, price/barter varies depending on travel time. Meet me in Grand Junction/Fruita/Clifton/Palisade, CO and it's free. Heck, meet me in Palisade and we can stop at a winery or the distillery for some free samples. Palisade Brewing also has some good food and drink.
Here are some pics for you. To go along with your PM.
I like the idea, but my balcony is just too small and too awkwardly laid out. I don't have the tools, budget, or patience to try to squeeze a 1m dish on the balcony along with the 90cm and OTA antenna, AND keep my wife happy all at the same time.I tried the 90cm in the corner where the 1m is, and it would still let us sit at the table, so I could have 2 90cm dishes. The focal length (and positioning) of the 1m dishes just doesn't work. I
could buy a different antenna to try to save space, but I have other things to spend money on right now.
Here's how crowded it is:

(second photo shows the newer CM dish on... a mount of sorts...)
I can't rotate the NPRM for the 1m (green in photo 1) because the support bar hits the bottom of the dish. Elevate the dish, and the balcony above me blocks some of the signal. Put it higher right by the railing and I'll have neighbors (and wife) complaining.
