"Fish Tail" barrel release lever.

[Dean Romig]

The Fish Tail top lever is rarely seen on the larger frame Parkers as the frame is wide enough on these guns to allow the opening of the gun with the right hammer at full cock without any interference between the right hammer and the straight lever. It is my experience that guns of frame size #1 and smaller more often have the Fish Tail top lever.

Look at pages 25 and 26 of current Parker Pages. The B on pg 26 is a two frame, and the D on page 26 is a 3 frame.

Best, Austin
