The early 1980s Shimano Deore "Touring" group could use the TA chainrings, too. However, their crank arms were different, with no indentation {see scan below} ... a few years later Shimano adopted the Sugino 74/110 mm bolt circle and dropped that style.
BUT... I do believe that someone else in Japan (like "SR" maybe?) did also make some dead ringers for the TA crank arms. Might want to check if the cranks will take a standard 22 mm dust cover. - Boy, wouldn't that be convenient.
