I love it when people leave the cabinet alone so it looks its age 
Only 6 months behind though Nino? In spite of all recent events I would have thought 2 years.
BTW I played a 1958 GTB sunshine game today and all I can say is "old school is best school"
This game looks like fun too. Lucky owner.

In terms of restoration updates - 6 months.

Workload - 2-3 years. Collectors have obtained the same patience level as I have - which I thought was not possible. 

I would LOVE a "Sunshine" - beautiful machine. My "Miss Annabelle" will do for now.

In terms of Bally games from this era - Bow and Arrow is a VERY good player. Similar to Aladdin's Castle - Gameplay is excellent. Not in the sane league as Wizard or Captain Fantastic - but just as much FUN.
