Hello. New to the list, and I was unable to search the archives of this list (function was not functioning, I think it had a coming soon message). So I hope you accept my apologies if this has already been covered... I was wondering if anyone on the list had and could email me a "comprehensive" list of cylinder mfgs both us and non-us. And if anyone knows the name(s) of an expert in the catalogs of each manufacturers. I have "edison" covered for help with those catalogs, but the others? For example, maybe someone can point me to someone who has researched the columbia catalog, or someone who has researched the lambert, or the US indestructible, etc. I am trying to do some research on the breadth of manufacturers and the approximate size of their catalogs and to research quirks with their catalogs (duplicate numbers in particular). Any way, thanks very much for any info or way pointing! [log in to unmask]
