New in Box Vintage DynaTech Blade Racers, huge set - Race Cars inna Clear Tube!

Description

Greetings - I am very pleased to offer this very rare vintage DynaTech (Canada) Blade Racers racing set.  Basically it's a couple of 'slot' cars suspended in clear plastic tubes and includes a very large set/layout (see pic).
it appears to be brand new never used although i did not assemble or test it.  (basically given it's new condition i'm not messing with it)
as a kid i was a slot car racer, so i will mention that over time the contacts (on the cars and lesser degree the track) can oxidize - best to clean these is electronic contact cleaner (spray), pencil eraser (vinyl best) or small wire brush.  may or may not be necessary.
All shipments must be signed for, we are not entertaining any porch pirates!
