This is a specialty tamper for Bellman CX-25 and CX-25P coffee makers. It is also suitable for for vintage Benjamin and Medwin, Elebak, Vesubio, etc type stovetop coffee makers. These machines look very similar to the Bellman coffee makers and in most case use interchangeable parts. The flat face of the tamper measures 70mm. Ordinary tampers cannot be used with these types of coffee makers as they do not have a hole in the tamper face to accommodate the shaft that runs through the Bellman type baskets.
