Aeromodeller, February 1971, page 101, Mick Wilshere's World Engines advert:
"Super Tigre G20/15 Diesel R/C - £12.00" (the plain carb version is £9.75), and there were very many similar adverts through the seventies.
Our American friends didn't necesarily read Aeromodeller.
The R/C G20/15D was available up to 1965 according to Chinn, but discontinued. Must have been reintroduced a few years later.
I've been through the AM index, combined engine tests, Google, and ads in some of my AM collection and can't find any other reference to the ST G20/19D.
It's a bit like the legendary G15 Diesel, very hard to pin down.
Guess I'll have to wait till something definitive turns up.
