Hi namesake ,
I can’t make out the field, but judging from the supporters (two lions regardant), it’s possibly the Swedish coat of arms. If that is the case, I suppose Carolus Rex could be any of the Charles’ (X, XI, XII) that reigned from 1654 to 1718, unless this type of sword fits in the period of the reign of Charles IX (1604-1611)
