Thanks for your helpful response. First question of the "more questions" 
would be : when you say "1950s  OS version available in Potlatch" - 
where exactly is that available? I have done most of my editing from my 
own GPS track logs in JOSM, but I have used Potlatch a bit and have seen 
an options dialog where you can ask for a different background, one of 
the choices being something you can type in for yourself. Is this what I 
want and if so what do I type in here? Thanks

Bogus
