This would be a grail build for me.. Very envious! The decals always remind me of The Partridge Family (dating myself here).
Like you, I would have expected the weight to be a little less. My lightest frame is a 58cm Peugeot with Super Vitus tubes that I measure at 1791g. That said, I don’t get worked up over what amounts to be a few ounces. I figure there is that much variability in scales, frame sizes and frame setups (i.e. with or without dropout screws, binder bolt, cable guides, etc.)
Looking forward to the final result.
