Instructions for the KS017 F locomotive kit.  You’ll need to create an account to download the 40 odd pages of fully illustrated instructions, but download is otherwise free.

This kit is for the pre-1880 locomotives built by Avonside, Nielson, Vulcan and Yorkshire.

For the later long frame locomotive built by Dubs and others (Neilson, Stephenson and Vulcan) see KS018.
