Here's a veteran Royal Enfield. I believe a 1913 Model 140 3hp 425cc v-twin. The little inlet over exhaust motor was supplied by the Swiss firm Motosacoche. The Model 140 was unusual amongst British machines for having a v twin engine of smaller capacity aimed at the solo market rather than the usual v twin sidecar hauler. Also noteworthy was the glass oil tank on the saddle tube, though glass might have seemed a bit delicate it was a neat practical idea that worked in practice and it was always easy to check your oil level.
