I don't know purpose of this subject of ammunition, but all types of the Bavarian cavalry have it. Possibly it is a ramrod. There are many drawings where there is this detail
I now complete fine details and I correct, in the next few days I will send to the customer, I think that at the end of the month there will be a release. But, I can't tell surely it.
It has just come to me what the metal spike on the Bavarian Curassier is for. I think it is hammered into the vent hole of the enemies guns so as to render them useless and unabled to be fired. Hence the old saying, To Spike his Guns. I believe all Cavelrymen carried them. Unless of course anyone out there knows different.
