These circular calculators have been re-manufactured
to the traditional design as used extensively in the sixties and fifties
for navigational rallies. You will find one invaluable for working out time,
distance and speed calculations quickly whilst on the move. Used by myself
and several other competitors on the 1990 Pirelli Classic Marathon, it was
constantly in use to check that we were within our maximum average, i.e.
not going too fast and liable to attract early penalties. Printed on long-lasting
white plastic and available now from me. Suitable for miles and kilometers.
