This is a 501 red-line model, but since it was used and there is almost no printing on the inner tag, it is impossible to tell when it was made. However, if you look at the part where the contraction rate is mentioned, you can see the two-digit number + the letter "%" faintly, so this can be judged to be a red-line model.
Gently tapered, just like the 66 model. It appears to be somewhat roomy from the waist to the area around the thighs.
