I have no clue what gun this is. It’s non operational(the bolt doesn’t move). I have no idea what round is made for it nor is there any markings.

I have identified the rifle its a old 18th century black powder dutch rifle. now that i know what it is im on the hunt for missing parts. nothing is going to be worked on /fixed. except the replacement of missing parts.
Id like to thank you all for your hard work of identifying this historic piece
