I looked for one in your collection for reference, but didn't find one. Will you, perhaps, be adding one in the near future?

A CMT MC-II? No, In my collection/database there are only calculators of HP - accessoires excluded.
My money is too limited to also collect other brands, even I have one or two non-HPs ....
