Here are the clues:
We are transported through time again. We end up at Fort Hayes Kansas in late summer 1868. The locals try to have us committed to the nut-house after hearing our time travel story.
US Army Brevet Colonel George Forsyth tells us that we can avoid being tarred and feathered if we join his new Army controlled civilian scout unit. His second in command is Lt Fred Beecher.
We quickly join up and are told we will be heading into Colorado.
The supply Sgt issues us each a wide leather belt looking gizmo with a snap hook attached. Some folks are issued something that looks like the top leather section of a cowboy boot.
Then he has us load pack mules with Blakeslee Cartridge boxes. We look into these boxes and they have around 10 metal tubes with some sort of stubby bullets inside. The cartridges look like they have a copper case and seem to be rimfire. This stuff is not new and seems like it was made a few years before during the civil war.
The Supply Sgt tells us we can get extra ammo from the Armory Sgt. He also mentions the numbers 56-56. He then sends us over to get issued our firearms.
We get to the Armorer and he tells us we have 10 minutes to grab our weapons and get out.
He has four of five types of rifles and carbines and ask what type ammo we have been issued.
If we guess wrong we will have to clean the latrines for a week. We are told that we will be riding towards the Arikaree river in Colorado in a couple days if we stay out of trouble.
Based on the appearence of the ammunition, the Blakeslee ammuntion boxes, The wide leather strap and the fact we are mounted volunteers.
What is probably the type of firearm we should claim, and what the heck caliber are the darn things?
