Legacy Decks
These are just a sample of the legacy decks back in the 1970-80's.
Information on some older and downright old decks exists on lawnandgarden.manualsonline.com where I believe that possibly a past or present technical support person or someone else having access to this information has made it publically available. Many of the older manuals have notes written in them by hand before they were scanned and converted to the pdf format for Adobe Acrobat Reader.
