    I'm looking for some help, please. I'm building a 7mm S&D 4F. I want to detail the backhead, but I'm having difficulty identifying what parts I need. I've trawled suppliers catalogues, but my problem is that they mostly do not have pictures of the items. I don't know the names of the various valves and fittings so can't work out which ones are appropriate I've got the 4F profile and other pictures of the backhead. Can anyone point me in the right direction please?
    Many thanks. Pete

    Don't forget the Armstrongs were RH drive unlike standard LMS 4Fs.

    Hi JB. Cornwall side of Plymouth.
    Problem is not just seeing one but translating what the parts are called and how that relates to the suppliers' catalogues. I've tried 2 suppliers already but have not yet overcome this hurdle!
    Thanks for your reply, anyway. Pete

    Thanks Col. As I noted to JB above, the issue is understanding what the descriptions are in the suppliers' catalogues (usually without photos) to what is fitted on the full-size version when I don't know the names/functions of the parts. Thanks for responding. Pete

    Yes, and finding a decent right-handed steam ejector is another problem! Pete
