Need parts for HP arbor unit. B-12 or similar - buy/trade

I'm restoring a Highland Park cab machine (Model B-12) which is missing one of the lower trays (water tray below the wheels), and the corresponding hood. It is the one for the single wheel (on the right end of the machine) and should be about 4 or 5 inches wide. While I can fabricate one out of tin, I'd obviously prefer to have the original material if someone has pieces of a unit that could be parasitized. I have another HP cab machine that could be used to provide "trade" parts if you have needs on your end. It is a complete machine so it could be a replacement or addition to your shop. The model number on the latter is unknown but its comparable to the B-12 except it has a double water tray on left (9.5") and a wide tray like the B-12 on the other side of the bearings with a tray that is 13.5" wide, and then room for a buffer. While the original configuration of my restored unit had only 2 wheels in the 13.5 " compartment, I've managed to squeeze in 3 8" wheels.
Note: my unit is on a work stand and has a 10" saw on the left side, but I'm relatively sure the B-12 was sold as a stand alone arbor unit and only sometimes paired with the saw. I'll try to post photos for info and clarification a bit later today. Tom
Obviously ideas on other alternatives are welcomed. Anyone knowing the location of a HP catalogue online that would help clarify model numbers and original configuarations is welcome to add it to this thread as a service to others dealing with partial machines. Cheers. Tom
