Searching for Linebaugh built 45C & 475L- blued with stainless base pin

[Badubet69]

I know this is a long shot. Years ago I had worked out a deal with a gentleman from the left coast to buy his 3 gun set produced by John Linebaugh. John had built him a matching 3 gun set with John's stamp of '211' by the trigger guard. I purchased the 475 and 500 and took delivery maybe 15 years ago with the understanding he would sell me the heavy 45 when he felt like he was ready. I lost touch with him about 5 years later and was unable to contact him or his family. He was a bit secretive and off the grid. I assumed he passed due to the health issues we talked about over the years. Other than the stamping I know for certain the 475 and 500 has stainless base pins on blued guns. John has run out of blued pins at the time of the build and had promised to replace them in the future. I currently have the 500 and after loosing contact and giving up hope; sold the 475 to a gentleman in Texas I believe in a moment of weakness (and despair). I'm trying to locate the other two now and try to put the three together as a set. I know it's a long shot. And help would be appreciated
