Thanks everyone for the info on the 20 gauge No. 205. This gun may be somewhat rare but it was a train wreck when I got it. The screws were all missing or ruined. Whoever had attempted to take it to pieces had not known enough to raise the lever to remove the triggerplate. They just pulled on the wood. This broke the stock top and bottom and severely bent the opening lever. Thankfully the barrels are perfect and all other parts are ok. Hopefully will be a nice light gun for my wife. Plan on using 3/4 oz. RST loads since it is so light. My wife and I usually chat with Gournet and his wife at the Vintage Cup so I will be sure to let him see it.
