Here's my 67-1, vintage of April, 1978. I obtained it from the estate of a neighbor who passed away at age 100 a few years ago. It's in perfect unfired condition; I'm pretty sure it was kept in a sock drawer as a "house gun." The red ramp front sight and black rear sight are distinguished from the no-dash version.
I had one many years ago when I was a neophyte reloader, and I bulged the cylinder with a massive overcharge. The thing held together, and I learned to read the powder scale more accurately since then! I sold the gun, stating that it needed a new cylinder.
These are some of the best .38 special K-frames ever made.
