I think 2851 is the right model, anyway. A wall mount, 6 button, Western Electric.
Would prefer any color other than beige or yellow.
Also if you have any WE 2565's in anything other than beige, blue (unless there is a model that isn't the "sky blue", I don't know if they offered anything in a deeper blue) or yellow.
Which I guess pretty much leaves white, black and red as my options. If it has to be beige... well.. OK.
Rotary or push button isn't that big of a factor.
Western Electric is a must though. Used is preferable, as long as it can be polished up. I know of sites where I can buy NOS or refurbs on all of these items, but man.... pricey.
Thanks
Matt
