Great advice Nino - I am always wary of project games and treat them as "wired and fused wrong until proven otherwise".
I also heard of a US game claimed to be from a private collection in Europe. This game apparently was obviously US from the coin door and other US spec matters. The purchaser could so very easily have been killed - beggars belief that someone would be so desperate for a sale to allow that sort of risk.
Yes - I have seen a few of these recently. Definitely not from Europe, and definitely not from anyone's collection. I'll see if I have pictures to demonstrate the issue.
I have no issue with project pins being sold into the market, as it gives me at least a day's work per week to convert, repair and quote on the machines. It is disappointing that sellers hide behind the "project" title when they know games are missing MAJOR components such as entire drop target assemblies - yet advertise them as "complete". This is no safety issue, but the machines are misrepresented.
