I have a '49 Clubman--I believe that the Lenton Clubman was only made in 1948. My '49 has EA1/597mm wheels (with original alloy rims). I've ridden it quite a bit, including over some crazy hilly terrain out in western Mass. I set it up with upright bars when I first got it as a chronic neck problem made that more comfortable for me. Last year, I converted it to drop bars, but that really reduced brake leverage (essentially, the brakes were just suggestions for stopping), so I went back to upright bars. It did look cooler with drop bars, however:
