Case 580 SuperM backhoe pin movement

Hi, I'm looking at used backhoes and came across one advertised as coming with two front buckets. The standard one and a larger material bucket. I wasn't getting a good vibe from the seller, sometimes it's hard to tell if you are being fed a line or if the person is genuine. After I had tested it out I asked if he ever had the extra bucket on he said no, I then asked "It does fit right?" He then said he never had it
