Photo request

I am asking for any photos or pictures of the “Spam can” type of packaging used by the USSR and it’s communist allies, especially China. I am in the process of trying to catalog and identify the various types of “can” and their method of being opened, marking variations, etc… I am also very interested in pics of the various “functional types” ie: tracer, API, etc… and their particular can markings. Any and all contributions would be greatly appreciated. Post them here or email them to me at: sweetvt(at)comcast(dot)net

Many thanks!
