Your subject is "average frame weight" but you're talking about Reynolds 653, which is a more exotic variety.
I have about 15 bike frames here, that will fit either my spouse or me. I'd say that they're "average" in that most of them are Reynolds 531, a couple Vitus, a couple Columbus. Most of them are built by reputable folk. I've weighed them all. Overall, I have to say that 6 pounds (2724 g) is a darn light frameset. The very lightest, in that 6 lb area, are a 60 cm (CTT) frame from 1950, a 55 cm Mondia cyclocross from 1977 or so, and a 53 cm Motobécane Grand Jubilé from the same year. All the rest, up to 63 cm, are clustered around 3000 g to 3200 g (6.6 to 7 lb), with an outlier, one of my favorites as it happens, at 3600 (8 lb!) -- seamed straight-gauge tubing. None of these are "work bikes" or other heavyweights.
