Cox .15 Special?

Thanks for the confirmation.
Cheers

At the risk of being pedantic-there was no such thing as the 'TD .15 Special' ..there was the TD .15, the Cox Special .15 and the Special .15 MkII-in that order of manufacture...mainly due to usage showing the TD .15 was a bit lightly built in the cylinder and failures -cylinder cracking round the exhaust port were appearing in use-Cox's solution was simply-and sensibly to beef up the lower cylinder OD slightly-and thus the Special 15-essentially just a product improved TD 15.The single exhaust schneurle ported Special 15 Mk2 was the result of a lot more R&D and the final development of the TD intended to maintain Cox's competitiveness against threats such as the Super Tigre G15-but fell short with the imposition of the straight FAI fuel requirement ca 1965...
