Luggage mounting system for R18 bobber

Where can I buy this Bobber luggage system?!? Holan does not answer…
sorry, I was very busy (I very rarely visit forums now). We were tasked with developing luggage systems for the CE-04 and C400GT.
Coming back to the topic, the luggage set visible in the photo is for the fender from Wunderlich. It doesn't fit in with the others
update: a prototype of the Classic cover for the top luggage system for the Bobber has just gone out of production. This is a masterpiece of the designer. Notice how well it refers to the lines of old racks. After removing the luggage (bag or top-case), the cover can be placed on the rack and, if necessary, removed in one second. The final version - black, maybe also in chrome.
