Re: [TCML] approximate value of these items

Wow, I guess now I feel very lucky I managed to snag 3 12/60 and a 15/30 in
pristine condition for $80 total! Granted this was 20 years ago, but it's
great to learn how much they have appreciated in value since that time -
and they are still in perfect condition and work beautifully (never used
for TC duty).
