The first Invincible was completed in August, 1923 but was first cataloged in 1926. It was offered at the princely sum of $1,250. Over the years the Invincible has taken on a shadowy mystique and was more of an unfounded rumor than fact. It has only been in recent history that the Invincible has come to be seen and photographed.
In addition to being more lavishly engraved and checkered than the A1 Special, the characteristic Parker recessed hinge pin is not present. There are gold birds inlayed on the sides and bottom of the frame, combined with fine scroll engraving. Unique to the Invincible, the frame has barrel side clips on the bolsters and was rebated so the stock fit behind the frame to prohibit splitting of the stock head. The checkering and engraving patterns are superbly executed.
Invincible serial number 230329 is a 16 ga. and the other two are 12 ga.
There were three Invincible Parkers produced*.
This was copied from the Parker site, I guess the Invincible had side clips.
