hi
here is one of mine \
Serial Number 6362
Remarks: Shipped May 1952

Company shipping records show
this Serial Number was shipped
with a Round Butt Frame, 2 Inch
Barrel, Blue Finish and Diamond
Checkered Grips.
This is one of the first models with
the smooth ramp front sight.
This has the original numbered box.
I think that the date is wrong on the the letter
or else the factory had a lot of frames made up
and serial numbered.
