I received this from Samstag. Probably quicker to modify a cheap 17mm wrench.
Doug,
Thanks for contacting Samstag Sales. We have this on our order list
, but we are not selling much of this brand. It may be 2 months before
the list is large enough to release the shipment. I will put you
on the list and send a quote as soon as we have this in stock.
Best Regards,
Andrew Poston
Sales Manager
