Unfortunately it's not all original. The footswitch had a late 70's date code, the pot was a Dunlop from the late 80's, and the jacks were both replacements (nice switchrafts though), and the rubber feet are newer. I've repalced the footswitch with a Carling for true-bypass and put in a Fulltone pot, The circuit board is untouched however which is the most important part. Compared to the later Cry Baby (can style inductor) the top logo is a little bit fatter and has a bit more top end but not by much, but it's also noisier (hiss-wise). Overall the two are extremely similar. I have a new Area 51 pot on the way to put in the film can wah (which has the old Dunlop pot in it now), which will make it a better comparison. Also, the top logo board has a 100K resistor in parallel with the inductor whereas the later wah has a 33K, which will make a bit of difference as well. The thing I like about the top logo over the later wah is the pedal seems to have a bit more travel than the later more usual Vox/Thomas Organ/Dunlop style pedals. It's nowhere near as much as a Colorsound and maybe not quite as much as a Fulltone Clyde, but definitely enough to be noticeable. I'll try to make some clips later if I have time.
Nice pics too
