The certificate is posted in the OP.

I do think your price estimate is reasonable given what we see. The legs are a real head scratcher. Don't know why he would have ever swapped out it the original legs to begin with.

My machine is in slightly nicer shape (similar playfield, but better cab) and only started to receive serious interest when I dropped the price to $6,000. My game also came without any bullshit origin stories.

If you read the thread though, I modified it accordingly and placed it for sale at $6,000. The $7,100 was the Pinside suggest price and was clearly outdated as a result of the vaults and such.
