Pa, I leave you to make your own mind up on the use of the Carry Handle but you should read this first:

Yugoslavian soldiers with Dutch M20 Lewis gun WW2, note the handle and carry strap...

Thanks Ironsides, it confirms the carry handle was introduced only after WW1.

In other words, the pose won't work well for any WW1 figure. Regards, Pa

I echo the sentiment:
'hoping for a 1914/15 "Summer" set of Serbian infantry.'
This is a very exciting prospect; I look forward to it intently, offering figures, not only for the Great War, but also for the Balkan Wars.

Looking at the photos and these are far better than any competitor products.
I would imagine the Greek-Turkish War 1919-22 is more likely for a secondary use of these figures if they follow the same pattern as the first set.
