With a separate box that says HP-41C application pac/mathematics pac on it. These have sold for a fairly high price! The calculator manual has December 1982 printed on the inside front cover so I expect it was manufactured then.

It has 5 functions, 20 keys, and a VFD (vacuum fluorescent) display. The power source is 4xAA. The calculator was made in Japan.

The HP-35 represented a number of firsts; it was the first "pocket" calculator produced by HP and the world's first scientific calculator. It was introduced in 1972 and disappeared about 3 years later.
