Actually it was only HD that threatened their rim supplier. Crocker had to get their rims from Indian after that. Crocker had a deal with Indian and actually suppled a few parts to Indian such as their steering dampeners. There's two Crockers in northern Minnesota sitting in a shed owned by an old dude that won't part with them. The Crocker factory is still standing in LA. I took a photo of it about 10 years ago or so which I posted on this site back then and somehow it showed up on the Crocker website.
Not being a dick here but do a little research and you'll see what the big deal is about crocker. He and paul bigsby (look him too he's a genius) built crockers in LA . they offered a money back guarantee to anyone who lost a race to a Harley or indian. there were only about 200 crockers built but no one ever claimed the refund. HD and indian were so scared that they threatened their wheel and tire suppliers to make them stop selling to crocker. from then on he had to sell his bikes as kits, without rims and tires. there were only about 200 built so they are very rare and a complete bike can be upwards of $250K. Lots of innovative stuff and very fast. paul bigsby 's hand made guitars are super rare and worth more than the motorcycles. he is also the inventor of the bigsby tremolo , used on electric guitars.
as far as dale walksler, I've never met him but on every video I've seen he comes off as a pretty cool guy in my opinion.
