Bought 3 years ago in near mint state: a LB No.4 Mk.1*.
All numbers on wood, receiver, bolt and magazine matching the number 43L56xx. I replaced the simple 300/600 flip-up sight with a standard Britishicon Mk1. Barrel bands, butt-end and magazine are nicely grey manganized. Grooved upper wood. 2-groove barrel, but a crack shooter.
