I own a Westley Richards try gun. According to WR they have only made 6. Here's a few photos that I have saved. I can't take anymore as the barrels and action are off getting refinished. I asked WR when it was made and they came back with 1879. Not too sure on that. It has ejectors, single selective trigger and damascus barrels. I only have the one length extension for 15". They were made with a small suitcase full of them.
