There's most likely a good reason that replacement gears, and/or non-standard ratios aren't being manufactured these days. The old law of supply and demand, plus the likelihood that no manufacturer with any sense at all would tool up to produce parts for such a small, specialized group of customers comes into play. There's probably a bigger market for buggy whips, and whalebone-reinforced corsets than there is demand for those gears!

There is definitely a more lucrative market for pairing those two items together in certain circuits of society.
May have to borrow the boy's 3D printer...
