I own War head to head...harder than heck to find info and parts for it. This one I had never heard of till last year.
It would fall into the unpopular game / rare to find working games.
Owned and restored the hated Mario Andretti 1120 units (low by todays standards) - PF swap - trim- legs = it got the works.
Interestingly enough I sold it for $1600 and saw it less than a year later at auction sell for under $900.
Looked and played excellent...almost bought it back. Pictures are on IPDB.
