I conducted a Google search for an obsolete service repair part and found Kauffman. Kauffman Family Tool Repair was very helpful even to the point of giving helpful suggestions on ordering the proper items

Needed a difficult to find guard for a Bosch hedge trimmer. Part numbers had been superseded by Bosch and no longer available. Kauffman had 1 of the newer part numbers in stock but it was not clear whether it fit. Kellie was very helpful by sending photos and taking measurements to assure a fit before I purchased. I ordered the part on a Tuesday afternoon, it was shipped out Wednesday morning, and I received it Thursday afternoon.

Excellent service!
