Hydraulic cylinder part numbers-location?

[Jim in N. Texas]

I took the dipper cylinder off an old 580CK backhoe Model 33 and could not find a part number stamped on it. I disassembled the 4-1/2 in. cyl. to compare the seals, etc with my parts manual. There were a couple different cylinder part numbers used on the 33. The gland was in pretty rough shape with the inner seal and o-ring rotten. All that was left of the outer seal on the gland was the metal pressed piece. The inner inch wide thin sleeve was in pretty good shape. Does anyone know if there is a part number stamped anywhere? The cylinder has been painted over in the past so its hard to see anything. I was hoping someone might have some advice. Thank you.

I forgot to add that none of the parts diagrams match what I disassembled.

Jim the gland should have a # stamped in it and you can identify the cylinder by the gland cnt
