rock (P-P blocks full name) lists numerous brands and PN's.
I don't think M-B makes hoses, just marks up the price for their brand stamp.
I don't think URO makes hoses, just prices them affordably.
If you are excessively fussy about rubber hoses, expect many issues maintaining your car in the future. Must be a bit resourceful to keep these as a daily driver.
Whatever hose you choose, always put a spring in the lower radiator hose so it won't collapse under water pump suction. I coil some stainless-steel wire (Harbor Freight).
