1914 DWM arty/4" WW2 "HZA" rework

[318is_Parabellum]

Thank you for having a look at my rework.

A couple of questions I still have...

I have seen the same exact HZA jt3 'stick eagle' stamp on other rework lugers. I have never seen or heard of the eagle and swastika over the HZA jt18(?) stamping in the final firing proof position? The stamping itself appears to have been double-struck, and is a bit difficult to make out.

--Upon utilizing the search function, I have found some references to the HZA jt18 stamping. I still wonder how unusual the full eagle and swastika HZA jt18 stamping in the firing proof position might be...--

Interestingly, the take-down lever (as can be seen in the photo) is marked both on the front (military) and on the underside (commercial-style?), as well as the side plate. The safety lever also is marked with the last two digits of the s/n on top. Is this a feature of WW1 lugers? I'm more familiar with WW2 P. 08's.

Thank You!!
