I just received these two brass grip frames back from Zane of Lone Star Custom Grips. The birds head frame is for a old model Ruger and the brass bisley is for a new model but I have a set of Clements old model bisley parts in the box so it could go on a new or an old model Ruger. The wood came from a friend who lost his house in the Paradise CA fire of last year. If you have not had Zane make you a set of wood or horn grips yet, you need to get in line.
