I have seen a few originals and if they had carving on the forestock it was of the incise style. All of them had the distictive "V" shaped flats to the ramrod groove forend shape. There isn't a lot of room for much else on them. I got to hold a very nice Schuler from Bucks Co. at the Washington Historical Arms Makers Guild show. It had very nice incise lines carved on the fore stock, the entry pipe and barrel tang. It almost looked like there could have been some wire in the bottom of the grooves at the tange but I didnt have any magnification to verify this.
