Anyone know when the Beeman R11 changed from a side slide safety to the push through version common in more current r11's or hw98's? I picked up one recently and was surprised to see the slide safety. According to the hw database, it was born in 1993. Anyone know off the top of there head when the R11 came into existence?I'm sure that info is readily available but I'm hoping some knowledgeable airgunners will share there R11 knowledge and experiences. This new to me needs some cleaning up but I figured they don't make the Beeman version anymore and it's a classic airgun.Thoughts?
