I have what I believe is a 701 as it has good figure in the stock w/ drop points.The barrels are,uncut,27"s w/a tight Ic & mod.The barrel marks are NB which puts it at 1962/serial #1323XX= 1961.The rib is marked "Carlton Model" Russell Hillsdon,Chichester.It is a 2 3/4",3 1/4 ton gun w/ejectors & auto safety,straight grip.The wt is 6lb 10 oz.This is the 3 rd 700 series gun I have owned and all have given me good service.I would like more information on the "Carlton Model" reference.I'm unable to post pictures.
