I hope this post works as after years of lurking, this is my first attempt.Can anyone post or PM me,the supplier of a pen holder built in the US.It holds various pens at about 30-45 deg angle to vertical,from memory fits a 1/4" chuck,appears black anodized body,it acts like a castor would be the best describtion in action.Sells about USD$ 45 from memory.Has adjustable spring pressure.If I remember all that, you would think I would remember where I saw it .wouldn't you? Alas old age takes its toll.
