Does anyone know approximately how many Skyliners are left? Epesially 1959's?

I can find production numbers for all 3, but no estimates on survivors
This question always comes up at car shows!

1959 Skyliner weight = 4,064 MSRP $3,346 # built 12,915
1958 Skyliner weight = 4,069 MSRP $3,163 # built 14,713
1957 Skyliner weight = 3,916 MSRP $2,942 # built 20,766

I've never heard an answer to this question either. My reply when folks ask "how many are left?" is "not nearly enough". I wonder if the IFRC has a total quantity of retractables based on data plates that were reported from current and former members?
