I put this up here after discusing with the owner and didn't know it had also been posted on the Dutch forum, where Peter

Thanks for this Trev and Peter. That's helpful, if a little disappointing. It seems like a substantial piece. What exactly is meant by fantasy marks and what was the purpose behind them? There seems little doubt that this is silver and well made and I imagine must have been done by a silversmith with the capacity to hallmark his work. Would the reason behind inventing marks be a way making the the piece appear older than it was (so if made in say the 18th C, an attempt to make it seem 17th C or earlier), or was there a cost to applying the marks which the maker was trying to circumvent?
