Does anyone on the list have access to a pair of Swiss made Sieber tubul ar tires that would have been available around 1948 and would you consid er selling them? Since I doubt that I will find any, perhaps someone wou ld recommend a tire that would be appropriate for an old Sieber track bi ke and indicate if you have any for sale. I guess I could go with someth ing later, as long as they look appropriate. Any help would be appreciat ed as I am totally unfamiliar with the tires used by track bikes in the old days.
