[Austin W Hogan]

I think this Folsom order has been shown before. There is a note Top Action Ext Rib at the upper left. The orders on this page are in the 26 - 29000 serial range.
The first top actions appearred in the upper 24000 s/n range. 26145 has an extension. I think TPS estimates the number without extension at about 1000. There was a top action for sale at Vintagers about 5 years ago that did not have the extension.

Best, Austin
