Since I just finished restoring a 1249, the pictorial of the work is now uploaded to my website, under Service Tips / Restoration 1249. There are three sets of pics. The first seventeen are from the dearing ring repair for repairing the lift ring (59) fails.
The next fifty or so are the fine tuning and calibration which is carried out similarly on each unit serviced. The last 180 or so pics are the actual restoration process.
If there are any questions arising from any of the restoration processes shown, don't hesitate to ask.
