I think we've already confirmed the later track pics are PID and original shots from York but the car likely ran Keystone too?
Love to see any more pics, whatever track they were taken at...have you tried adding them to your postings using the advanced tab?
If any easier, can you post a link to where you found them or are they included somewhere in this collection of Bill Truby pics...
