Regretfully it is not mine. However a bike of this particular model back in 1973 started my never ending love to antique motorcycles. We were in high school then when in mid spring a friend of mine spotted one in a back yard of a residential home about a mile from where we lived. The owner planned to use its wheels to build a cart and sold it to him for the value of these wheels. I cannot remember the actual price but for todays currency it was maybe $200. The bike was not running but it was COMPLETE even with original paint although strongly faded. We were kids then with absolutely NO idea what to do with it or knowing even remotely competent adult who would give us a single advice. We were just on our own. We took it all apart then, cleaned, painted and put it all together expecting it to run. Amazingly we used all the parts and there was not even one "unnecessary" washer left. However, considering our "knowledge" on the subject there was NO CHANCE that the motor would ever start. Then the summer started and we left for vacation having it parked in the internal parking lot of the apartment building complex we lived in. Unfortunately after our return three weeks later the bike was gone. Early Spring next year I bought my first bike. It was 1949 BMW R35. I loved this bike. The IB I currently own I bought 9 years ago. Now you know why.
Anyway, back to this Royal Enfield; we did not even know what model it was. Only after mrunderhill1975a mentioned about existence of model WD/C I googled it and to my surprise I found the posted images. I instantly recognized the bike. It bothered me for years. Yes, its motor had side valves. This is the reason I posted these photos. Thank you mrunderhill1975a .
