About 1960 there were a plethora of designs being kitted, by FROG, KEIL KRAFT etc, all very similar to GMA's Peacemaker, published in the AeroModeller in '59.
This model, the Talisman, (28" span for a 1.5cc motor) was kitted by FROG models, check out 'The House of Frog' website, they were making models in the '30's.
Back in the '60's I could buy one these kits with one weeks paper round money, so I built a few

I got paid 17/6 (seventeen shillings and sixpence, for 7 mornings, 5 am-8 am then school

) a week, the price of a Talisman, the tank also came in kit form so I learned to solder at an early age.
James is fine after his crash with a road sign, which put a 2" gash in his head! I'm told he kept the Doctors an nurses entertained.
