This looks like a Murphy Custom Leather rig to me. The owner had an email once that was OldDanRiver something. This is a great price and a super nice rig
I would recommend a neurosurgeon and not an orthopedic surgeon. I had a couple vertebrae fused in my neck with a cadaver bone a few years ago but nothing like you guys are talking.
best advice I can offer is do everything that they tell you to do and don’t do the things they tell you to not do!
I use 140 grain for 38 and fill the case pretty close to the top and compress. I get the bullets from Missouri bullet company and they put BP lube in them. You have to email them and make a speical request as they sometimes dont have in stock.
Good luck
