yes, yes, no etc
I had the Mamod steam roller (no canopy) - ran in meths, family still have it somewhere.
Not mentioned was the Philips construction set (http://www.girdersandgears.com/norelco.html)
My set is almost complete save for a couple of small parts and a chipped large plastic wheel that my sister broke due to pushing the construction pin tool at an angle, can still recall the scene now, pristine set to that point, then that broken wheel taunted me for the rest of its life. Bitter! me? mmmmnnn.
Our family was too short of funds for most of this stuff so any kits that would need building then frequent batteries or more repair outlay never got started as I could not stand the long construction run for five minutes of fun before having to put it away, in kit form at least the potential is still there.
In the 80's or 90's i would sometimes fire up a CB at Xmas to see who had got one as a gift (at least give them some response from a call) or look outside to see the new bikes teetering along with small concentrating kids atop.
This year for modern comparison I looked out and could see virtually nobody, even checked the skies for the milion drones expected to be sold this year, nothing, I guess the toys are inside things now. I did see one lad with a new bike, full suspension, full sports downhill kit with expensive helmet, could not help feeling how much simpler our wants were.
