Hi Mike, thanks for your response. The gun is a Holland which the seller said was a Harris Holland. It would be nice if it had the New Bond Street address on it since there were other Harris makers. The barrel wall thickness is 0.024 right barrel and 0.028 left barrel. It would be a shooting gun and it is nitro proofed. It is around $3000 and I do have pics but am unsure how to display them. thanks
