I thought the same regarding the rampart gun’s markings, thanks all! And I believe I also recognize the first matchlock in post #6 as the one sold also from Bruneau, last April if I recall. A very nice piece I thought; but alas I dropped out of the bidding when the price + premium went beyond $10k.
The suggestion that the first piece comes from Styria is very interesting! I believe the matchlock I have coming to me is also from that region, probably one of those examples from Frondsberg.
