A bit confused as SN does not match up with Browning info for this Grade I with rear wheel sight. According to Browning, there should be a number before the "T" but there is not. SN is T52xxx. Looking at chart, the only thing I can come up with is 1956-1960. There were no SN's thru 1955, in '61 they were changed. Doesn't say how what they looked like from 55 -61. Just curious. There is no SN on the barrel as there is on my Grade II, which is obvious to be 71Txxxxx. If anyone is inrterested in either Grade I or Grade II that has been redone at Art's Gun Shop in MO, send me a PM. I don't use either and never really have. I'd love to see them go to a youngster that could enjoy them for a lifetime. Just an FYI

The single digit year code preceding the letter started in 1961 and went until 1969, when the double digit year code replaced it. It changed again in 1975, when browning moved the production to japan. You have a pre 1961 which starts with a letter, T meaning long rifle caliber.

Agreed, looking at the chart, so it has to be between, 55 and 61 since there were no numbers prior to 55. Wondering if anyone thinks it is worth it to have Art completely redo it. He did a Belgium made Tbolt fro me that had a salt stock and it turned out beautiful for about $700 if I remember right. It was handed down to me
