After much searching, I finally found a brass pneumatic bell to finish out my truck.
I might not get to actually be hands on with it until late summer since I’m still working overseas and I’ll need to find a push/pull valve for it, but it will be fun finishing up my install with it.
Okay so I don’t even know if I’ll be able to get home this summer due to contract restrictions with the job. I’m still waiting to get my visa so I can leave and re-enter the country, so we’ll see what happens.
