What's odd to me is the single TA style road width (3/32) chainring, with no provision for attaching inner rings. I thought the model 49 was a two ring crank from the start. ------------------------------------------------------------------------------------
One sees these all the time on bikes in the V-CC News & Views, for it was a common way to set up a bike in the 1950s, when British riders often (but by no means always) used only one chainring. The number of rings to use on a 49D was up to the individual, and TA even offered a four ring combination. Remember that TA made rings for the 49D and cranks of the same pattern from Williams, BSA, etc. for some years before they made their own cranks. Chain rings not drilled for mounting an inner ring have been available from TA probably for decades. I have one on my bike.
