[Austin W Hogan]

That Invincible frame has the side clips brazed on, and was described as "green" by Babe when he showed it to me.
According to Robert Runge, the serial number was affixed to frame, barrels and fore end iron when the rough parts were soft fitted in "the first warehouse" to begin a gun. We showed his sketch of this in the article on numbering several years ago.

Best, Austin
