Merry Christmas everyone.

Today I won a Model 60 on the GunBoker for $355.00 + $36.00 shipping.

SMITH & WESSON NO DASH MODEL 60 SPL 38 SPECIAL : Revolvers at GunBroker.com

I have two questions today ?

1.# It has a pinned barrel and I am wondering what year was the last year of the pinned barrels on theses revolvers ?

2.# Also what does the term "No Dash" mean ?
Thanks
