Ive spent a pleasant evening exploring the contents of the bag of detailing bits that came with my Ebay Athern loco. It would seem having to add the extras (like handrails) is not unusual, this has turned out to be a good buy as looking at the wheels it has never been out of the box

Anyway here is how it looked before

After adding details like, handrails, horn, headlight lenses, number board lenses, bogie details, couplers and hoses.

It makes a big difference to the appearance, the parts were well made (stanchions and rails individual steel pieces)

Just out of interest I googled "Chessie 4167" and came up with this

A bit dirtier than mine !
