Here are straight front+rear bumpers taken from an early 70's W108 sedan. The chrome is very good to excellent, the car must have been garage kept. There's a shallow dent in rear bumper, this is mostly concealed when the black rubber bumper strip is in place. The two "X" marks show the quality of the chrome underneath the grime. A little bit of chrome polish and elbow grease will get you a great shine. $65 for front bumper and $50 for rear, plus s/h.
I also have a straight radiator shell, also with great chrome. However there is some staining visible on the top surface that unfortunately I couldn't get out by hand polishing. Still suitable for a daily driver. For $45 plus s/h.

Also here's the radiator mesh grill. The mesh and trim strips are straight and complete. The center vertical trim strip has a shallow dent mark (see photo) that could be tapped out by a patient hand. Still suitable for a daily driver. NOTE - the grill badge is not included in sale, its long gone. For $35 plus s/h.

Finally a seat base spring unit, believed to be from an early 70's sedan. It does NOT fit my 1969 W111 coupe, but is similar in design and construction. If you have sagging or broken seat springs in either front seat, it's a simple DIY project to swap the spring units (which I did for my coupe when I found the correct piece). I can supply measurements and search for part numbers to make sure you're getting a part you can use. For $45 plus s/h.

I can email jpgs for each part, sorry I can't fit them into this thread.
