Hi...newbie here, with another gun from a grandfather!
.38 Special, Serial Number 26XX.
You can see the ID on the barrel in white; I'm pretty sure my dad did that with Liquid Paper (the sights are also touched up that way).
The story was that this dated to WWI, but I honestly don't know. Was passed down from my grandfather to my dad and then to me.
Thanks in advance!
