They most certainly are Oldtimer, or at least they were the last time I deer hunted Pa in 2012. You may want to check on that because a Game Commission Officer is the one that let me know they were off limits. Could be he misinformed me but I can't imagine why he would have. He flat out said that piebald and albies were off limits. And I read into why from his statements.
As to the other "backward regs", No Sunday hunting, manually operated firearms only, I think they finally caught up with the times and allow crossbow in regular archery now but not sure, and not to mention the totally inept DMP.
