Looks like 'rear' square lamps, lamp irons, cylinder thingy (which someone else will need to comment upon, thanks for the photo), Newer lamps, older style gas lamps in black, skirts which will look nice at one end at least, prototypical couplings, I think, and various hoses on the top edge. So I'm no use to you on that cylindrical oil/water/lubricant thingy with the 'spout' Plenty on here will know though
