I think the serial for the first is either 63 or 67-699. Perhaps you can tell us more? I think I was told once that it was an original Mig killer. The other a/c serial ends I think in 414. It appears to be a refugee from a battle damage repair unit as it is covered in patches. It’s been in a dismantled state for at least a couple of years.
