In the early Browning grading system this gun was referred to as a Grade VI. Reference Shirley/Vanderlinden, page 163.

In the later Browning grading system this was referred to as a Grade 4. Reference Shirley/Vanderlinden, page 139.

The serial number establishes that it was made in 1929 so I would tend to call it a Grade 4 as identified in the 1930 catalog mentioned earlier.

Also the checkering pattern is typical of the later (grade 4) style.

Wonderful gun, is there a story behind it?
