A complete Wayne 40A, with no problems and solid sheetmetal, is worth $1800 to $2200 (Maybe $2500 on a REALLY nice one), depending on patina. This one is missing the visi, face bezels, faces, and something is obviously defective on the top, or he wouldn't have that globe holder ring attached. Scobie sells cast iron repops of the bezels at $150 each and the faces are $50 for a set. The visi is another story---you might find one, but I bet it will run around $450 or so??(Scobie sometimes has repops) and after these parts, there are the small tags and badges and levers and cranks that need to be there, but we can't see if they are or not?? So take the highest figure and start deducting for ANY parts you might need, or set your sights higher and buy a complete one.
Same goes for the MS 70, but you have a smaller base price to start with. Use $1400 to $1600 on the MS70, and start deducting!
