Thanks for your PM, I agree with you the aircraft windscreen was most probably modified to remove the central windscreen post for the single pilot conversion. Looking at a LC-126 undergoing restoration I agree the structure shown in your photograph matched that of the aircraft being restored. I found the attached photograph of N195SE which is a L-126C now in civvy colours. I would be interested to know how many single pilot LC126s were built.
Yours was an interesting challenge which got the old grey matter working.
