If there aren't any distinguishing features to suggest otherwise, I'd say it's a Pea Picker built from factory original parts.
Twenty years from now, it will be considered an original bike.
For the guys in the know now, it's up to them whether or not they consider it to be an original Pea Picker.
I agree with Abe, that now that we know that it wasn't originally issued as a Pea Picker, it's a collector built Pea Picker.
With that said, you did an outstanding job, and I'm sure that had to be a labor of love.
It's a spectacular bike.
