Going by your other interests my Uncle John Cox in Victoria has a 1915 version one of these Aussie Healing Peerless V twins. He took on the 800km ( 500 mile) plus Bicentennial run from Sydney to Melbourne in one fixed gear, years before he finally found the 3 speed Sturmey Archer gear hub for it. He is still going to Vintage and Veteran rallies with his toyhauler and bikes from his collection in his 80's.
