I am looking for an extractor for a Savage 1903/06/09. Extractor mounts in a slot in the top of the breech block. The only one I can find is available from Jack First (#714-15A). Have any of you done business with Jack First, and do you have experience with extractors for this model. I understand there were 2 styles of extractors for these models, and I am not sure which one First has. I will likely call them Monday to see if they can educate me. In the meantime, does anyone have thoughts on this?
