thread dredge, but if you are interested, look at the catalogues for what was on offer
1939 Brown Bros Catalogue grips start at page 128 and tape is on p320
1948 Brown Bros catalogue grips start at p80 and handlebar tape at p225

for tracking uses over time, have a look through the Holdsworth Aids catalogues on the V-CC library The 1961 catalogue has the handlebar tape varieties on p40 (cloth and embossed plastic)

I find looking through the bikes on Speedbicycles gives a good understanding on what was used over time.
