Top job  especially for your 1st effort too.
Yes, making your own stencils and painting the cab/headbox is a lot of work but as you've found, well worth the effort .

I was very tempted to buy this game when it was on EBAY. Great to see it being restored to its former glory.

Got any pics of the playfield now you've cleaned it up ?

Yes, I love fault finding these old games too.
If you own an EM you really need to learn how to read a schematic and if you have a manual as well it really helps .
