Thanks Mike!
As for the McLaren. It's the old Entex (huge) 1/8th static kit released around 1977/78 in tandem with the Fittipaldi's Lotus 72D. I think Entex wanted to try and horn in on Tamiya's strangle hold on F1 modeling with their awesome 1/12th scale kits. The two Entex kits were also licensed to the Japanese firm Eidai/Grip who marketed them in Asia. Revell brought the molds, but only released the Lotus 72D and that's where the story gets nuts. The McLaren molds were either mistakenly destroyed or lost in the transition to Revell. One of the old timers at Revell told me that he was almost certain that they had purchased both sets of molds, but could not account for them not releasing the McLaren as Hunt was something of a world-wide sex symbol star at the time. Be that as it may, the Lotus 72D is easier to find and can be had for about $600 now. The McLaren is considered one of the true a "Holy Grail" kits (right up there with the ITC F-108 Rapier) and can go for as much as $2200. Although with a little effort and patience it can be found for a bit less.
Someone sculpted the James Hunt figure for Wim Van Vlasselaer in Belgium at Bestbalsakits.com to go with the kit, but it's a bit pricey! Looking at some of the amazing work on this site I fear I may have dropped the ball a bit on some of Hunt's skin tones. I do sincerely believe that any one of the great artists here could have done a better job than me.
