This piece is on the left and it has a *huge* upper wire groove lip and more rounded domesides. I have shown it beside the standard No 40 for comparison. From a distance it looks almost like a 154 top, but it isn't.I suspect it's some dometop mould variant or, possibly they reworked a mould that had problems in the upper WG lip and made the top bigger. If anyone does know anything about this variant, I would be interested in knowing more on it. It sticks out like a sore thumb in with all other 152's. Only issues are 8 flaked drips and a small blemish on the UWG shoulder to the rear side. Displays VVNM.Not rare but interesting..... $7 + shipping.
