Hi Spiridonov,
Now back to your question about ramrods of portable handguns/arquebuses such as the small Hussite barrel of ca. 1430 which originally had a tiller stock: a stick stock usually had no provision for a ramrod and the latter had to be carried separately.
As we see on the Polish gun of ca. 1500 though, this problem was sometimes solved by drilling the tiller/stick stock out and storing the ramrod there (last picture).
Other clever solutions were mounting the ramrod on the left side of the forestock when a hook made a ramrod chanel impossible below the barrel, or make the hook with a loop for the rod to pass thru.
Samples attached.
Best,
Michael
