And here the G250V-G260 service kit, which fits the R109 if converted to "balanced", as almost all are nowadays:

If your 109 poppet takes the puck seats, you can use a leather punch and a strip of EPDM to make them, as long as you don't want to convert to balanced.
Almost all the service parts are O-rings except the HP seat. Aftermarket HP seats are readily available. My favorite place for anything O-rings is www.theoringstore.com. There are annotated assembly diagrams for the MKV, 109, et. al. and you can find the right O-ring sizes there.
As for the 109 poppet seat, they are easy to make (see aquaregia) earlier. I also DIYed a brass collar to keep the poppet seat in place. It is in a thread on the subject somewhere. I made a lifetime supply about 6-7 years ago, so have forgotten the details.
Exhaust Tees are very easy to make serviceable ones. I just use a piece of clear vinyl tubing with a hole just big enough for the metal flange. Stays on WAY better than the aftermarket silicone ones.
One-way exhaust valves are common items. 2nd stage diaphragms are likely common also, but I bought a lifetime supply and haven't looked lately. No, none of it is for sale. The diaphragm cover is easily DIYable - I made mine by casting, but 3D print with TPU would be a much better way to go.
