I have for sale a 45-70 on a martini action (not a Gp). It has 26inch numrich arms half octagonal barrel and open sights. It's a nice clean piece. It does not have scope mounts as yet. Nice trigger!
£600.00 with 50 pcs brass and lyman dies. Pm for info - the rifle is at the smiths at the moment and I don't have any pics, but I will try and sort some asap.
