Now in my early fifties. I grew up on motorcycles, over the years I've had so many twin cylinder European bikes I can just barely recall them all. (Ducati, Moto Guzzi, BMW, Triumph, BSA, and my beloved Norton!
Clocks, (especially marine chronometers) and vintage pocket and wristwatches. (especially Railroad approved pocket watches)
Vintage tube audio gear, McIntosh, HH Scott, Altec, Dynaco, etc. I match these relatively low wattage amplifiers with highly sensitive horn loaded loudspeakers like Klipsch La Scala, Altec 604 or 755, Lowther, etc.
Shotgunning, I love my 1964 Browning Superposed! I have others too.
German cars. I have nothing to say publicly about this!
I also love my Oak manufacturing and Ford gum machines!
