@Littlereddot Thanks for the responses.
In answer to your first question - which may make what follows easier to understand - I originally viewed the site using Firefox on my Samsung Galaxy Tab, which is Android. I have no idea how significant any of that is. However... all I saw under the ffordes name was the search box. The red secondary menu bar didn't appear at all. In reading your comments on navigation, and your references to other menus, I turned the tablet to landscape orientation (which makes a difference with the West Yorkshire Cameras site). Still no other menus - only the search box and the big "Brands" drop down list. I then thought I'd try the three parallel bars that appear top right, and that generated a hitherto unseen menu. If you hadn't said anything about a menu, I probably wouldn't have found it. This look more as I would expect a site to be. It's also present - without any extra intervention - on my Win10/Firefox desktop, although I don't recall seeing it before this evening. So site navigation is easier than I thought, and I'll check the site over. I do think that perhaps there should be some clue that there is an actual menu available though. I have absolutely no idea how to get a screen shot from my tablet, other than by photographing it.
My searches were more in the way of trials - as you should know from my purchase history, I wouldn't be looking for any more ETRS film backs, at least for a while as you've just sold me two. I was more interested in seeing if I could find the 35mm back that I thought would be there. Clearly, I needed to know the designation rather than just saying "film back" in the search engine, but possibly you might consider adding extra generic keywords to aid searches. The Nikon search was mainly because I felt it reasonably certain that something should turn up. If the menu works as well as the old site's, then I don't see a need to use the search function again. Especially if it's necessary to know manufacturers' designations. Some of the Leitz ones are rather obscure, to say the least!
From what you've said, I can appreciate why change was needed; and also from what you've said, it
seems that the new site could be better than the old. I've lived with the old one for a long time now, so it's rather familiar. All I have to do now is to discover something that I really really need and look on your site for it. Your comments about few toy shops being left is true; happily I have one local one but there aren't many. In practice, there are only three I look at on line if I want something, and ffordes is one.
If I have any further thoughts after a good look round the site, I'll let you know, either here or via email.
