I've been looking to complete my original Ludwig, Leedy, Slingerland and Wurlitzer catalogs, pre-1960. If you have any for sale/trade or know someone, I am happy to pay a premium and/or finder's fee. I will also buy in bulk to get the ones I want. These are great reference material for my writing (Modern Drummer, Not So Modern Drummer) and just plain cool lol!.
