Ron,
I have heard of unmarked examples also. Let me ask this, we know there are variations in the suspension loop and ring, are the ones with the ribs(like the gold and silver in my other thread) deschler made and all others are smooth like yours. If that is true did deschler have a patent on that design and the others built off that design but made a slight differnce in the suspension loop to beat pat infringment.
