Deasey 707 Question  

After seeing the restored 707 at the Reading Reunion last week I started to look for 2 photos my father shot at EWS at the end of the 1971 season.  Is it possible Deasey had 2 similar looking cars in 1971?  The top photo is Chamberlain on a one race deal the week after Stan left.  Duct tape covers Stan's name on the roof, and the lettering "BIG DONKEY" is over the wind shield.  Also, it's not real visible in this image, but there appears to be a patch on the hood where the engine was mounted forward for tracks that didn't allow huge set backs.  Also the headers look like they don't belong to the Cammer.  The bottom photo is one week later, final race of the year at EWS 1971 with Opp in the car.  No "BIG DONKEY" over the windshield, or patch on the hood and it looks like the SOHC Ford headers.  I've also seen other pics from 1971 with or without "BIG BONKEY" on the car.  Once again, is it possible Deasey had 2 cars during the 1971 season?
