Oooops, Universal Designs is the correct name, not Productions, sorry.
I agree that David's (UD) zipper placement is a little off, should start about an inch lower on the jacket at the top, and the bottom end of the zipper should be about an inch closer to the center line of the jacket.
The waist stripes are also off a bit, but from his later examples of the waist stripe detail I believe they will be much better in the production versions. I'm hoping some of the zipper placement and such will be slightly helped with the adjustment of the cut in the body of the jacket for the final version.
The color is off on the yellow in the stripes, and David has already admitted that it is the same color used for his X1 and that he was not changing it. Should be much more yellow than orangy gold...but I believe once weathered properly and dirty/greased/ashed up a bit the stripes will look correct enough.
I also believe the cut of the sleeves is off a bit and have already gone over this with David. He has a lot of extra room in the bicep and no curving forward of the sleeve as it goes to the cuff like the actual motorcycle jacket of Bates does. Luckily this extra room is where I plan on taking it in a bit to make the sleeve curve properly once I get mine.
He makes a good quality product, but I think some slight details are always a hair off.
Still a much better bargain at less than half the price of a Bates.
