PRC-9 Finishing Touches

ORG | CH Table painted and ST-120 A/PR harness

Found a manpack harness at Apex Gun Parts Gun Parts & Accessories (apexgunparts.com) who seem to have a wide selection of various parts. The WWII era belt was from Overlooked Surplus in Leavenworth, KS Overlooked Military Surplus (wwiigimilitarysurplus.com). Overlooked Surplus has a very interesting selection, and I will definitely be stopping by there more as the budget allows. They have an old field desk of particular interest to me.

The painting was done with stencils I made on a Cricut machine, which did ok but difficult to work with the tiny lettering needed. I got it, but it took a couple attempts. The ORG | CH table above the dataplate I assume was for operators to jot down frequencies of units they worked with. Small space to write, however, no idea how practical this was in the field. The other marking was “Pointer Adjust” and the nearby dial does move the frequency dial needle. I assume they found a known stable frequency and adjusted the needle to match that. These radios were continuously tuned, as opposed to later PRC-25/77s or modern SINCGARS where turning the tuning dial stepped a set amount of kilohertz.

Pretty happy with the final result and it is now ready to go in the truck when it gets back from service. I still have to work out the antenna and mount, since the installed antenna wont work well with 2m radio and the flex antenna stuck on the radio isn’t hooked to anything – it also is tuned for MIL frequency range. The flex antenna does look nice though. For the vehicle antenna, which will connect to the BNC Aux antenna connector, I am looking at a Firestick 2m type which should look similar or at least not too out of place. It comes in black and the conductor is spiraled over the fiberglass whip, but hopefully is fine after paint.

Good, Cheap, Fast – Pick One

Normally this is pick two, but for old military vehicles, it seems to be pick one (and probably best to pick ‘good’). I have been fortunate to find people that are familiar with this era of machine and find this project interesting. I don’t think the truck will be ready for Winter Field Day 2023, but it is getting closer.

M37 with rebuilt engine newly installed

I bought the engine hand crank as an accessory, while attempting to start the engine with that is very risky, it is good for turning the engine for timing and such. I am glad I got it for this purpose. The radiator has an access port for this so even with the engine completely assembled for operation, this crank can be used. The crank itself wasn’t very expensive, I think under $100 or so from Vintage Power Wagons.

Looking forward to getting the truck back and on the road.
