Tom, you have a LNER police helmet plate worth about £50 in that condition. A common badge, the LNER Police were a big old Force (1450 on establishment). Their badges turn up regularly on Ebay and go for £70 tops. The Force was viewed as quite forward thinking for it's time and sent their recruits to Hendon from the 1920s. The Force amalgamated with all other railway Poice forces in 1949 when the British Transport Commission Police were formed. I know a sprightly 90 year old who was in the LNER Police. Talking with him has beeen fascinating as you can imagine. You have the 2 piece version. Th
