I have had in the past NOS Cal Custom & M/T valve covers that were from the '60'early '70's. Even though new and boxed up, from age, they oxidize and loose their shine somewhat and become duller. Yours looks a little too shiney. Also, if that is the box from the manufacturer, based upon the box's condition the covers are not that old. Probably 2-8 years old. The NOS Cal Custom box also had white cardboard and it was severely yellowed. I bought a set from CP 3-4 years ago and the box looks identical to yours
There is a guy on ebay selling the Sunpro chrome gauge cups and he is getting $25-40 a pop or $44 buy it now. Every couple weeks he will list 3-4 cups. You can go to the Sunpro website and by them direct for $13.99 each-which is probably what he is doing.
Those early style Lakewood ladder bars look like the ones you got off of me. They look good painted up. Of course if you want them to look like they came from Lakewoood you should of thrown alot of dirt into the paint, missed areas and have lots of runs.
