Now for the spare parts :(

The knee lift-screw bearing is dead, it looks like a 3306-2RS Double row angular contact 2 rubber shield item - 30mm ID, 72mm OD, 30mm W

Can anyone confirm that please?

Also is there a good source for the tubes and fittings for the lube system in the UK, might replace the lot as it looks like some of the points on the knee lift ways were doing nothing, luckily i always backed up with the oil can;)
