The 1870 horsebox is now painted and in service.  Once primed I liked the overall level of detail, the top hinges and the dog box end show a slight bowing out but not severe enough  to merit a substantial alteration.  I think it would be in plain coach brown by the 1900s, compartment interior off white and a simple bench seat added. Lettering is from the HMRS sheet.  Some light weathering to bring out the details.

A couple of posed pictures.

The start of a racing day special perhaps. The new horsebox is followed by a CR Dia 73, built 1907 and a LNWR Dia 436 from the late 1890s. Just about plausible then.

I’m still a bit unsure about resin printing. The model has worked out reasonably but I am concerned about the brittle nature of things like buffers and steps. My preference would be etched brass steps and sprung metal buffers, though I appreciate that would increase costs and might not be viable for low manufacturing volumes. Perhaps too printing a model in a number of smaller sections would result in a greater accuracy ?
