The original trimmer pot is made by "Tocos", the markings on the back (of mine at least) are "102 6X 82", the 102 corresponds to a 1k pot. The pin spacing is 2.5mm by 2.5mm with the single pin at the front.
Quick update on the pots. Got some in the mail from digikey and these 2 seem to be a good replacement . I read the value of the 1 good original pot I have and it measured 861 ohms. So, 1k will definitely work. Both the 3.3v and 5v pot are the same part so it seems I'm good to go. Gonna hold off on swapping them for a couple days till my psu and sound Amp recap kits come in and bang it all out at once. For those interested, I included the part numbers for the model 3 pots in the photo.
