Collectanea
 

Not being a collector, I don�´t have to worry about resale value. What worries me here is that I�´ve just got hold of a Wehrmacht P 08 firing pin gauge . It seems that the firing pins on my Lugers all work well but are all too short (the story of my life). Or am I using the notches in the gauge incorrectly? Patrick

Perhaps if the pin touches the guage it is too long!
 

Patrick,


Or perhaps the one of the notches is not used for the firing pin point but some other measurement. Could you possibly repost this photo with a ruler in the picture so that we can tell how large this device is? I have never seen one before and I don't believe that this device is included in the prints available from Frank Rial. How about it Frank? Do you have a print of this device or any other information?


There are three notches in the guage. I presume that the ones on either end are for measurement of pin protrusion in the uncocked position and the one in the center is for determining if the pin point is the proper shape.


If you can re-shoot this photo please make sure that the ruler and the device are parallel so we can recreate such a device. How thick is the metal and what is it made of? How are the markings applied? are they stamped? Painted? etched?


Does anyone else have any information on this guage?

Could it be a Go/No Go Guage?
 

If the firing pin point should be between 1.10 and 1.35 mm long it would touch the 1.10 side and not touch the 1.35 side. Just a thought. Maybe the blueprints can verify the dimension.

Re: Could it be a Go/No Go Guage?
 

That�´s what I took it to be. I put the gauge on the scanner but it came out larger. The size is: length 49.5 mm, width 19.5 mm, thickness 2.8 mm. There are two in Bender and it is also in the G�¶rtz list of parts that are stamped. The writing is cut into the metal. The ones in Bender have two holes on either side. The ends of the notches on the side have been stamped so that they are 1.35 mm and 1.1 mm deep. The pin should protrude within these limits. The round notch is still a question mark. Patrick

Guess as to the "Round Notch"..
 

Hi Patrick,


I'll bet that notch will match the OD (outside Diameter) of the pin from the point it protrudes from the breechface to the tip of the firing pin. If it is "flattened" (and the guage won't fit over it - it will decrease the Overall length of the pin and its protrusion length (and be less then the 1.1 mm length on the guage). If the pin is narrower then that OD - my bet is that the pin would run the risk of piercing the primer casing when it strikes...


It's only a SWAG (Silly Wild A$$ed Guess) and probably not worth Frank's $0.02

Re: Guess as to the "Round Notch"..
 

... sounds logical. So that�´s got it all sorted. Thanks! Patrick
