It will be worth more without the foam grips, extension levers, rearview mirror and reflectors.

Bob Jackson has had a variable reputation over the decades. This appears just after the dark period, but its close. For a while, the bottom bracket shells almost w/o exception were distorted, it was re-tap the shell, check the shell faces, and when it was evident that over 1 mm per side was needed to get a square face, install a Phil Wood bottom bracket.
In a conversation with Bob Jackson about this in 1975, he admitted that some of the lad's were a bit heavy in clamping the shell in the bench vise.
