It wouldn’t have been very customizable. The mechanism uses gear trains with shared gears. The are physical constraints to what gear ratios work in addition to the constraint of integer tooth counts. The interdependency is inherent to the design.
But gear tooth counts are easy to change for a different ratio. This was not mass produced, everything was made to fit this machine. So the shared gears can change within the limits.
