I've got something similar, again with Viner decals and a 531 sticker, but the cross cutouts in the lugs suggest it's probably not a Viner. It's a lovely frame that rides beautifully so I suspect this would as well.
Mine takes a 27.2 seatpost which is a bit more consistent with Reynolds or Columbus tubing, no idea what 27.0 suggests tubing wise.

Good luck with the sale
