Your website editor is finding a lot of regimental photographs with no date attached. It might be a CO's parade, a salute a gun exercise, etc. Whenever I find one I try to narrow it down by the uniform worn or a recognizable face with a rank indicated. That doesn't always lead to an easy find and I end up going from yearbook page to yearbook page trying to match the elusive clue.
In order to provide a useful guide I've taken sample photographs from each CO's parade, each salute, each gun exercise, etc. So far I've done from 1950 to 1979 and placed the links on a page called, "What year was that?"
Check it out, you might find it helpful in sorting out some of your own Regimental photographs. Once you get them sorted out you can scan them and send them to me! Or put them in a shoe box and I'll scan them.
P.S. - Let me know if you find any errors on the pictures and pages posted to date. More to follow as time permits.
