Hi PossumBean
Your bag looks amazing - your Uncle was very talented. There are many others with immense knowledge of sewing machines on this site so I won't comment on that, but on the matter of servicing I use a Typical TW1-2BL20 for seriously heavy duty sewing and we have a guy who travels 200+ miles to our area to service machines every six months. You may be able to find a similar travelling service that covers your area, as these machines do need a regular service. Additionally, I suggest getting all the advice you can on how to perform maintenance on your machine - mine has a hidden oiling point we didn't know anything about until yesterday, and the machine is 20 years old! Not good!
Hope that's slightly helpful.
P.S. My service guy is in the UK so doubtful he will make a call to yours, sorry
