Anyone familiar with a Haenel Model VII air rifle? It's a .177 caliber break barrel spring piston type air rifle. I shot a BB at a 1x6 piece of pine and it almost penetrated it.

Tried to google for more info, but no luck.

Look anything like the Model III?

Not really, my description was off somewhat. It is not a break barrel design. There is a lever under the barrel that is used to cock it. The barrel remains fixed with a loading port that fits between the barrel and the air chamber.
