You peeked my interest so i did a quick check of nasa
to find the info and here is what i came up, this is
not a complete listing, unable to get the data for all
of the surveyors and the dry mass of the apollo 14-17
descent stages (which were the only part left behind).
Anyhow, here are my findings. I would be interested
to see if the completed list if anyone has time to
track down the remaining weights...

Data came from
http://www.fourmilab.ch/earthview/lunarform/landing.html

Russian When Dry Mass (kg)
Luna 2 1959 390.2
Luna 5 1965 1474
Luna 7 1965 1504

Luna 20 1972 5600
Luna 21 1973 4850
Luna 23 1974 5600
Luna 24 1976 4800

Apollo 15 1971 "11,463"
Apollo 16 1972 "11,457"
Apollo 17 1972 "11,463"

Apollo weights are only for descent stage dry mass
except for apollo 14 and on in which nasa archives did
not separate out dry mass of descent stage
