The cast iron Milepost made in 1819

"... Originally The Trent & Mersey had simple stone posts; there is still one left in Weston Cutting, and at least one (on the River Churnet near Consall Forge) on the Caldon Canal. Around 1818 the company decided they wanted something better and commissioned particularly attractive cast iron ones from a company called Rangeley & Dixon (based like the canal company in Stone). They installed these posts (one assumes from the R&D caster’s mark) in 1819. The 93 posts covered the 92 miles between Shardlow (rather than Derwent Mouth) to Preston Brook.
