Brodie's the real deal fabricator and so diverse. Ground up reproductions, straight restorations, big and small cycles, as well as world class bicycles. Racing & development, design of frames and engines coupled with machining his own parts. Generally he can and does it all...quite well and puts to shame most of the reality TV bike builders/posers.
Your correct in that building back to exact specs would fly in the face of new materials, techniques and updated design practices & engineering advances. Building a better safer transport in the process while essentially duplicating the look should be the goal of the re-creator not blind and unthinking duplication. Face the reality and deal with it...critics seldom build anything but their own sense of self importance!
Lack of information, at the right moment is frustrating. Turn down the wrong road and later back up, develops character I suppose, yet hinders progress towards a harmonious outcome. You've got a good handle on your Indian Tadpole Steve just stay real.
