[Austin W Hogan]

The Parker Story shows that there was an abrupt change in Parker barrels near s/n 70000. This figure was used in a Parker Pages article relative to this, and has been on the forum in the past. It is a frequency analysis of Parker 12 ga bore diamerters, showing the abrupt change with the post 70000 tooling.
The two large circles are from live bird guns; much similar to Super Foxes, but may have been post production re bores.
Best, Austin
