I accidentally bought a second one of these. So now I have a spare.
It took ages to arrive, and the cost from Amayama was $51.68 + postage.
Someone take it off my hands, happy to send it for $60 total paid via paypal or bank deposit.
Why is it revised?
The bracket has been updated to be in steel and not the plated (bronze looking) steel that reacts over time with the bodywork, especially given its location (spills and so on) and can create rust. Two bolts, move the bottle aside, swap and done..
