Kenner's Girder & Panel Hydro-Dynamic Building Set No. 11 w/Pump, near complete!

Description

Kenner's Building & Girder Hydro-Dynamic Building Set No. 11, in good working condition, and near-complete!
Condition is very good.  Pump works and all parts are included as listed on the box.  Only 1 pipe joint, 1 small tank part, and a few pre-cut lengths of vinyl pipe are missing.  Also, there are 11 color tablets left, as 9 were used decades ago!
The bulk of the parts - base tray, girders, tank parts, piping, etc. -- are still very sturdy.  As you can see from the photos, there are a few dings to the corners of the road parts, and it should be noted that the wall & roof panels as well as the road parts are fairly fragile plastic.  They were thin to start, and over the years have grown somewhat brittle.
Original box is in very good condition.  The top label has a small tear at the bottom, and there is a 1" tear in the upper right corner.
Original instruction booklet, parts list and other papers are included as shown.
