I need some assistance with two component timelines. I have a bike with steel chrome Dunlop special lightweight 27x1-1/4 made in England UK 266486 dimple spokehole rims. Could they be prewar or does the UK signify post war? How about Robergel stainless spokes? Prewar or postwar? I have my estimation, but won't suggest my thoughts pending your learned comments so as not to influence your reponse. I'll tell you the machine they are on after I have some feedback. Thanks for your help. Ted Ernst Palos Verdes Estates California, USDA
