Vintage Lot Of 20 Interlocking Robot/ship Action Figure

Lot of 20 pieces - vintage vending machine transfomer style interlocking action figures. They are made of hard rubber and have different shaped tabs that allow them to connect in several ways. I purchased these as a kid in the mid to late 80s and they've been stored away for years. The larger ships are about 1-3/4" long and have removable cannons that swivel.  Most appear new. Please see photos for more details. Make sure to check the shipping tab for more rates - Ebay doesn't always display the cheapest price first. Thanks for looking!
