Is there an online catalog or forum discussion for ww1 british food boxes?

Hi guys, I wanted to know if you knew where to find a descriptive photo catalog to correctly identify the various boxes of food or comfort items that I find here on the English lines. I would like to give a summary identification of what the contents of the various containers could have been and also know if they had a paper label or a silk-screen print so perhaps I could try with oxalic acid to reveal any writing. Here for the Italian cans we have texts edited by various recoverers or discussions in Italian forums that describe well what their contents were at the time. Thank you very much for your advice and suggestions Flavio

A few photos, apart from the usual square boxes containing meat

Any idea where to find references on English canned goods supplied by law but also for civilian purchase?
