I brought a full grain Schlesinger leather briefcase (current cost for a new one is $450) here to get the handle fixed. Fred suggested replacing the handle and I agreed because it was torn. The briefcase is about 14 years old and is showing wear so I asked Fred if he could clean it up. He said he could re-dye it and it would look good. So I said ok.
Here is my conclusion on the quality of the work: both handles got replaced. The old handles were of much higher quality and had a metal tube inside of the handles for stability. The replacements were skinnier and cheaper with no inside support--basically more of leather straps as compared to handles.
When I went to pick up the bag, the dye job was horrible, so they kept the case to redo it. They dyed it much darker than the original color--very disappointing! They took a full grain leather case and made it look cheap. Plus, the work was sloppy. There was dye on the buttons and hooks, which I cleaned off. It looked as if they spray painted it without masking some of the metal parts. I paid $70 and I'd say it was worth maybe $35. I'm really sorry I had them dye it. I could have done a better job myself with some shoe polish and leather cleaner. Now it looks like a different briefcase, and the case looks cheap--too late!
My advice is to be very clear with B&L as to exactly what you want and expect. Also, I found Fred to be kind of rude and not very pleasant. I will likely not be using B&L in the future.
