This is a moog provisional catalog showing all of their modular synths dated 1973. .I have had this for 20+ years, but it may be a copy..not sure.... ..Ask questions before bidding as sales are FINAL and as is...NO RETURNS ON SCHEMATICS or LITERATURE! I pack well and ship promptly. I ask winner to contact me within 24 hours of winning and have payment in 5 days or I relist. Don't be that guy and ask for a closeup of the schematic... I do ship international, but buyer pays duties and fees.  I don't lie on customs forms. Continental us ...Hawaii and Alaska are more, please ask. This will probably ship media mail.
