All About Pocket Knives

I recently purchased a 33 cm picklock with the tang stamp in the attached photo. This is a transitional Italian knife: bayonet grind, slip-in spring, high button, horn scales, and (maybe?) nickle plated bolsters. I've included a photo of the tang stamp, and wonder if anyone can identify it and the maker?

I can add additional photos if that will help.

Thanks for your help.

I'd say the lack of an answer indicates that it's one of the many mystery brands of Italian switchblades. I know I couldn't find anything about them. But I have seen it said that they are rare.

"Super Extra" could have been the Italian brand, or the brand of an importer. But even if it were possible to know which of those it was, the chances of knowing who actually made it (as in a person) is extremely unlikely.

Any chance of a full picture of the knife for us to admire?

here's another with that stamp: viewtopic.php?t=73505

There should be five images.

Make that six images.

Thanks to help from others on this forum, I've determined that the bolsters, button and safety are all nickel silver. I've also found that the liner uses "D" tabs for the button fulcrum as described in the extremely interesting and informational Switch Blades of Italy, Zinser, Fuller, Punchard. Turner Publishing Company, 2003.

I appreciated your help.
