heers68,

Given the ingenuity of many gunsmiths of yesteryear and today it is difficult for me to imagine that "blitz" action receivers were never configured to accommodate rotary cocking indicators. I don't own any and can't recall if I've seen one or not. It's not hard for me to imagine it being done because a typical "blitz" action receiver and trigger plate afford the real estate necessary to accommodate the mechanism if someone wanted to do so. I’ll ask around and see if someone can send us a picture. The easiest way to identify if an action is a blitz action or not is to observe the width of the trigger plate. As a blitz action has the lock mechanism mounting to the trigger plate they tend to be substantially wider than those of a boxlock. Also, generally the only screws you’ll see in the side of a blitz action receiver are the retainer and locking screws for the barrel lug locking mechanism. One other visual is that of the top of the receiver (behind the top lever pivot). If the gun is equipped with pin type cocking indicators the top of the receiver will run a little further back than that of a box-lock. I’ve included a few pictures from another post to show you an example.

Regards,
