1969 Camaro Chrome exhaust tips original takeoffs?

[bbbentley]

Eons ago, in that time called my youth, ahhh youth (I digress), I acquired all kinds of parts for my 69. Around 1980, a friend came up with a set of chrome tip T.pipes to trade me out of something I had. He was good friends with the parts Mngr. @ Campbell County Chev (Ky.) Years later and after poor storage, I dig them out for a CRG post. I am told that they are nothing special at the time. Recently, a few asked if I would part with them. I probably will as I do not have a late dated 69 (post May 69). Doing a little research, I am convinced these are actual assembly line pieces. Why? The Rh has no flange to clamp on to the transverse muffler for one (factory Rh welded) and the Lh, it has the Chrome dipped up so far with no welded on tip end evidence of assembly line again. Would like some opinions (educated) and if these would have more value over NOS or over the counter (I would assume)?
They are very solid and would clean up, I believe. To avoid confusion, I will put another 2 posts with LH in one, RH in other. Thanks sYc.
