I remember the gun was made in 1960 by the serial number,maybe it was a 28 no dash.But I'm almost certain that I had a dash 1 ,dash 2 and a dash 3 at the same time.It did have a 6 inch barrel on it.But this was 32 yrs ago and really no one seemed interested in highway patrolman's in the 1980's.At least in my area of New England.
