This seal, shown below, is characterized by it's rounded corners, and more glossy material.The USPC likely switched to this style due to it's better adhesive and easier manufacture.They did, though, change their seal design much more often than other companies.I am sure of the order of these stamps, but not sure in the dates.

The Later records not in combination set are sorted by classification value (I - Invention or A - Additional), then by classification symbol order ascending.

The records in each file are sorted first by patent number ascending and kind code.

Arrco has existed since the early 1920's (though until 1935 it was named, 'Arrow Playing Card Co.'), and is probably the second most popular manufacturing company in terms of quality and use.

I know much less about the exact dates of the use of each of the seals used by Arrco.
