ID this set: Rocket launch installation? While cleaning out the attic of my deceased cousin I found a plastic bag with parts that supposedly is a single set from late 70 or early 80's.

Actually there where multiple bags, each containing a single set. Some had the instructions leaflet and others I could relatively easily identify. They all date from around 1980. So that is why I presume that the one bag left is also a single set from that period. 

Sorry that I don't have pictures. I may add one later.


A large green ground-plate (about 40x30 nobs, I didn't count them exactly) with white printed markings where the first layer of bricks should go.  
2 pieces of straight blue railroad track.  
Regular bricks mostly 1x1x4 and 1x1x8 in blue.  
A bunch of white quarter-circle bricks and some (4) black ones + a white nose-cone piece. Would together make a small white rocket with a black band or black markings. A bit Saturn-V like.


It looks as if this would make a rocket + a base or launch-tower. The tracks are maybe part of a moveable launch-pad? There are no wheels to go with the track though.

Does this ring a bell for someone?
Minus the reference to the large green baseplate, could it be pieces from Set #358 - Rocket Base?

Edit:
A few original, used red baseplates can be easily had under $10 bucks through a few Canadian sellers HERE.
