Ever once in a while you can pick off a sleeper on Gunbroker. I have been looking for one of these for a while.

Just won the auction for this .303 Sporting Martini marked Halloway and Naughton. From the markings I think this is retail gun and not actually made by them.

I saw one of these for sale in France marked Bonehill and I think they were the actual maker. The French shop would not export out side EU.

There also was another similar in Germany, bit fancier that had been rechambered to 8 x5 7 JRS and the rib cut and claw scope mounts fitted. To butcher an old antique sporting rifle like this-tasteless. Beautiful rifle, ruined!

Anyway this new acquistion will go to the range when it arrives and we will see if it shots well enough to go elk hunting with me this fall.
