I bought some DA sidepulls I think in 1973, and there were DA centerpulls earlier than that, so I think DA may have been around in 1972, and 1970 isn't out of the question. One reason the bid isn't very high may be the frame tubing is unknown, but with those components, one would think the frame should be of quality tubing.
