I have a very similar sword i recently acquired.  Single hanger, 5 petal on sides & back. No numbers or characters.  In a separate note, is this a Japanese knot?

Greetings and Happy New Year. I was hoping to get an ID for the top-left and bottom patches. I'm thinking the top-left is Costa Rica or Nicaraguan National Guard. The bottom patch is probably Venezuelan.  Any help would be appreciated.

There are the 2 uniforms I've managed to collect so far. Woman's is Airforce, Men's is a Winter Sailor recruit

This is my first one, so not really sure.  Overlay on a black wound badge.

This is the smaller metal Totenkopf for the Panzer wrap collar tab insignia is it not?      

These RZM Walther PPKs were mostly carried by party folks such as NSDAP members or SA guys.  An issue Polizei pistol would have a police inspection marking on the trigger guard.  I have never seen a RZM with a Polizei inspection marking.   The holster wear could certainly include postwar wear and tear.  As a matter of fact I carried a Polizei marked PPK as a backup gun for years while on the job.  I know my postwar use would have certainly contributed to the holster and pocket wear.  

Richie is quite right that these old warhorses were mostly issued to Artillery units during WWI and this is what your butt markings indicate.  The markings on the left side of your frame indicate the maker of this Reichsrevolver and there may be a two digit number that indicates the year it was manufactured.     Neat old guns.

It definitely looks like that cap. Somebody must’ve easily replaced the patch!

Both are great, also The Story of Dr Wassell   Scott

I think the marking is for the 61st Artillery Regiment (2nd Grand Ducal Hessian), 4th Battalion, Weapon 26 and previously, the 25th Artillery Regiment (1st Grand Ducal Hessian)   I think these pistols were 2nd or 3rd line issue during WW1 but who knows if they saw any action. Both units were part of XVIII Corps which served on the Western Front.    

Here are East and West German enlisted caps. The pattern is close to the East German style. The insignia is easily replaced.
