1981 (PZ serial number) Miroku (model unknown) 12 Bore Over Under. £300 Doncaster, South Yorkshire.
30" barrels, 14¼" length of pull, fixed choke (¼ & ½ was told when bought but I don't have a choke gauge), mid and end bead sight, ejectors, inertia trigger, selector safety (pick over or under to fire first).
Look at the photos for yourself, my points; minor marks on forend, finish worn around selector safety, locks nice and tight (see in photos, top lever is well to the right of centre)
