Hello Mark,

I can say without a doubt that it is a "Very Nice Grade", congratulations on your find!

Seriously, if you give me the serial number I can give you the year of manufacture
and what grades were made in that year.

Best,

JC
P.S.: Pictures of barrels just front of flats will give the proofs it was submitted to. jc
