"Manufacturer: Marchant Calculating Machine Company of Oakland. The Marchant is a pinwheel machine that operates like the one described in the introduction. Originally two models were manufactured, the Pony and the Standard, which differ from one another in size."

Martin Reese in his book "Neue Blicke auf alte Maschinen" describes the development of the Marchant company and calculator models (page 118 ff.)

Pony

 

the Marchant Pony A has the physical dimensions of 30 x 20 x 12.5 cm (width x deep x height) and a weight of 6.5kg, while the Pony B is 32 x 20 x 12.5 and has also a weight of 6.5kg.

 

the Marchant Pony Special A/B has an additional control register.

 

Note: at some time, the mechanical principle of the Marchant Pony changed from pinwheel (and rotating cursors) to adapting segments (with non-rotating cursors). It is currently not known, at what time or serial number this switch took place.
