My guess is field kitchen for the top wagon.

Second one looks like the small carriage for a 37mm AA gun the Germans used in WWII, Sd. Ha 51 or 52 trailer. There are several that are similar.

I have no idea on the troops, but will guess Russian.

Oooooohhhh! Hope you are right. That would be really special.

I do like the one`s that make you think, two types of Russian field kitchens , WW 1 & 2 is my guess.

A wonderful brain teaser! Mysterious!

One can be a field kitchen, I presume. Tachanka? Unfortunatly no! Tachankas have 2 wheel-axis, but these have only one. The teaser needs to be continued....

The soldiers? Probably russian soldiers of WW2, civilians or militias? The balalaika is very russian.

You might be right about this not being a Tachanka, what made me think of it was the Wikipedia article on the subject with this image:
https://en.wikipedia.org/wiki/Tachanka#/media/File:Taczanka.jpg

It might well be the case that the vehicle in that image is not a Tachanka at all but rather a Russian MG transport cart, given this is material captured in 1914 (and the caption calling this a "turret" is clearly wrong). Regards, Pa

Pa, your foto shows really some similarities with the parts, but I hope, that it isn´t this kind of a Tachanka.

I have studied in the internet many photos of Tachankas, which were really different, but never before like this german captured Tachanka in your foto.

The first thing that pops to mind when looking at the pictures is field kitchen, Russian, WWI... although the cap on the fellow on the right looks like something prior WWI. Actually those two could fit into any scenario from Napoleonic till WW2.

Gulaschkanone - goulash cannon aka Russian field kitchen on wheels.

I thought it reminds me of a porta-potty (Latrine) on wheels. I could be wrong.

Classic Wayne. Love a hearty laugh on a Satdee morning!

Well this looks interesting. Oh, Strelets what teases you are ;)

I also don't think it's a tachenka, but I do hope you make one! i love the sculps and those figures look like they're having a great time. Can't wait to see the finished product.
