Thanks. Here’s a bit more I’ll share.
My finest P210 is the 1967 -6 model. Its actually one of the custom kits Sig sold back then. Came with the matching 30 Luger barrel and the entire rimfire upper assembly (from the P210-7 line). Its got the very rare factory full checkered grips that I believe were only included in these package deals.
At any rate, its quite a gem. I never shot it, because I believe its unfired outside the factory. You can see the test targets, one being 22LR.
My most valuable is the Heavy Frame from 1975. While the later CNC Heavy Frames are relatively easy to find, the forged Heavy Frames of the mid 1970's are a true unicorn. Only a couple hundred were made, with the vast majority being in Europe. God knows how many are still even around 40+ years later, but here's one of them in all its glory!
