Before there is a run on Lutz 252 slide rules, there are others with the same scale arrangement.
My Dietzgen 1734 and a Sterling 594 are the same with the S scale on the slide just above the D scale. A Dietzgen should be cheaper than some and a Sterling should be very cheap.
Any good slide rule can do what Greg is describing but the trig scales may be further away from the D scale.
