Houston, ive got a problem too..

Before we start, dont panic. Im only stranded in darkest lancashire, not space. My problem is only one of identification.

Ebay always reminds me of a tall, heavily loaded apple tree. You can stretch and climb to reach the highest apples, only to find that someone else pinches them before you. Or even worse, that the fruit that youve struggled to reach has a worm in it! Sometimes you find the sweetest fruit hanging on the lowest branches, within easy reach.
Ive just had a browse of the windfalls and bought two unusual toys for a few pounds. Trouble is, im uttelrly mystified by one of them. Advertised as "Triang/Marx?" Aircraft Carrier, i received this cool toy just this morning. Its about 15", has no makers marks at all, not even the obligatory "made in Hong Kong". It seems to be almost complete apart from the aircraft! At one end is what seems to be a launcher for a copter. Inside is a elastic band attached to a string which whirls the little red gear on deck. This looks very similar to the type of mechanism on the Triang Helicopter Launching Railcar. Does anyone have the slightest idea of age or maker ?
Next up is a slightly less mysterious toy, a Jimson Space Cruiser. I had thought I might have discovered another addition to the J21 'X' Series, but to no avail. Its a nice toy, if a little too retro for my tastes. Anyone recognise it ?
