This page contains almost all 'outline' and 'dotted' baseplates produced by Lego between 1965 and 1980. There were two dotted plates made after 1980, for sets 7838 and 6071, which are not included here.
If you need any, I have several baseplates for sale (351, 354, 358) through my store on Bricklink.
Patterns for set 080 are tentative, based on instructions and somewhat ambiguous photo's!
I'm still looking for reliable scans of the various basic set 080 baseplates. This set was sold with two different versions of baseplates, some larger, some smaller!
