I've only seen and handled one Tobin with DeMoya Steel barrels. It was at Jimmy Austin's beautiful old cherry paneled barn on the stearn and rock-bound coast. He also had a Krupp barrel 16-gauge No. 30 Expert Grade in there that day that I was more interested in. Didn't have the scratch to get both. The DeMoya barrel gun was heavy (bit over 8 pouunds) straight gripped with a single trigger. The sideplates were mostly stippled and one had a flying duck and the other a standing duck. There was quite a bit of rust around the trigger selector and that kind of put me off too. But, a very interesting gun, and unlike anything pictured in any of my Tobin catalogues.
