Hi Mark and Richmond,
I have often fired 'real' 400-year-old muskets from my collection.
Attached is a photo of me firing a combined wheellock and matchlock musket of ca. 1660, using the wheel ignition, in 1997.
The musket was almost identical to the two samples from the same series shown in the following photos:

Enjoy.
Best,
