So potentially the prospect of a group test with a standard MC28 putting out ~ 40 BHP
For a milisecond, I thought about offering my full power 21SP Rothmans (with the JHA Airbox Lid fitted )

PB should see Fastline for a wire-spliced MC21, I recall a PB Grey Import group test many years ago with a Cabin 21SP supplied by Fastline, but with a botched 'plug-in' delimiter from Japan which didn't actually work.
