Vicon cm 240 disc mowers

Are there any one with information on these mowers. My neighbor has 3 cm 240 mowers and we are looking into trying to make 1 out of 3. We have the serial numbers and the problem we have seen, the mowers are the same up until the last two series of mowers, which are 14052 and 14056, anything before this is different numbers. So my question would be did Vicon change the machines or was there some kind of sell out or buy out during this period.

 

 

Thanks Donny B
