The bike at the front. The Bedford truck is already listed. Norton 16H..over 100,000 made for WW2 service
With that many 16Hs built it's little wonder Messrs Pride and Shark in Stockwell were still selling such ex-WD stock around 1959/60 for £39-10-0 or so. Never saw many WD Nortons on the road but may well have mistaken them for M20s, of which 126,000-odd were made.
