I fell into this one. I took an extended lunch so that I could get to my indoor range and shoot one of my three recent purchases, a 10-8. Range store is almost empty and as I hand the man my pass I peruse the display cases. And there it is, sticking out like a holster worn sore thumb amidst the sea of dark gray and black autoloaders, another Model 10 HB!. Quickly determine it's a 10-6 and it's got it's diamond pc's. SN C778512 so I'm assuming somewhere between 1963 - 1965? I don't have my SCSW yet but I googled enough to read this date range in some old forum post. Price is good, good by my standards anyways, and I asked them to "hold" it for me while I shoot.

While shooting I texted my wife and basically had to sell my soul to get the green light from her. She wasn't happy. Got done shooting, came out and got them down a whopping $25 for a price of $325. Lot's of holster wear but as tight as it could ever be. And the grips look awesome. I've got another shooter!

My week old 10-8 is on the right. Oh by the way it shot phenomenal.
