This is a 66chain model 501, built in February 1980, near the end of the so-called redline model period. There is no sign of having been worn, but there is no flasher or guarantee ticket attached, and from the condition of the denim with some fine wrinkles and the deflection of the paper patch, it seems that it has been drained. This may be why the fuzz is a little more noticeable than the fully-rigid ones.
Straight, tapered from the thigh
paper patch
A paper patch with a CARE stamp. There is a deflection, which suggests that the water has been passed through. There is a perforation mark on the right edge where there is a little bit left over, indicating that it was a tear-off tag.
inner tag
It is noted that it has a shrinkage of 8%, and this, along with the chain stitching on the back pocket back, indicates that it is a late 66 model.
inner tag
The number on the third line from the top is "20 0 6", which indicates that it was made at the factory in February 6, 1980.
back pocket
Near-square-shaped back pocket. The arcuate stitch angle is also shallow.
back pocket(back)
It is sewn with chain stitch.
red tab
In the small e double-sided embroidery tab, the "V" is an unequal V.
bar tack
Black bar tack
top button
The type that has a lot of pots and pockets. It's pretty shiny. The photo is lost, but the top button is parallel stitched.
front button
Three, except for the top button. It's no different from the later models.
fly button
Button that is not a foot-long R with a pitter-patter.
top button (back)
Engraved with a "6". The top of the waist belt is chain stitched.

Copper-plated iron rivets. It's no different from the later models.

coin pocket
Coin pockets are used vertically and the other cloth is used horizontally. The back of the coin pocket is chain stitched.
outseam, selvege
It is sewn with chain stitch. The selvedges do not show much fading.
fabric
It's hard to judge the texture, etc., because the glue is still halfway through, even though it has been drained. As far as the back of the fabric is concerned, the weft is homogeneous. The neps are almost absent.
