Looks 30s to me, but honestly anything between 1925 and 1946 wouldn't really surprise me. Hansell or Mansell leather saddle, 'Made in England' on NDS crank, interested handbrake, fixed/free rear hub. Has faint shadow of a crown-shaped head badge or decal, and two faint logo or maker's emblem decals on the seat tube. Serial number placement reminds me of a 30s Phillips bike I had, but honestly this era is not my strong suit. Hoping the shape of the head badge decal makes brand ID easy for someone who does know these bikes better.
