I have an OT 90 M2 (BMP ) really excellant vehicle easy and great fun to drive ,they can be bought in Czech ex reserve with low kms.
dont know a lot about Abbots but all will have been sold off after a hard working life
the gear box is not that bad ,there are two air pressure gauges let the air build up in both till the needle hits the blue mark ,then you have enough air pressure .
