Hebel short barrel, unknown marking on bottom of grip

[SSG]

Hi there,
I might buy a short barrel Mod. Hebel with a (for me) unknown marking on the bottom of the grip,
R.N. just on both sides of the lanyard ring, if one can read one, the other is "over the head".
Has anybody an idea what the meaning is?
Thanks in advance!

could you please show clear photo's of the markings.

Sorry, that`s all I can provide, no better quality.

Side view showing maker, barrel length, etc. ? ?

[SSG]

sorry, you asked for photo's of the markings..
maker = LBJ, the seller doesn`t mention the barrel length in the auction..., see picture

Thank you. Well, I it is as you say a short barrel hebel flare pistol. The RN I have not seen before and can be an organization mark or mark ( initials ) of an owner. I have had a good number of LBJ marked hebels so it is not a rare manufacturer. Hebels were also manufactured or adapted with even shorter barrels for use with Tear Gas.

Thank you, according to "Signalpistolen der Welt" Nr. 1 there are 22000 pieces manufactured by Louis B. Julich. But this signal gun I don`t own (not yet ?)
I have two more Hebel, one normal length (JGA, Johann Gustav Anschütz, 55000) and one with shortened barrel AND shortened grip (EFB Ernst Friedrich Büchel 23000). So nothing rare, but I like pieces with matching numbers on the screw-heads.
Have a nice weekend!

I did win the auction and received the LBJ yesterday. As I saw before in the auction pictures, the "edges" are a bit "rounded", but for me it`s ok.
