Im like 99% certain they're 514's from that era. 99% Cotton 1% Elastane stretch, this gives the proper vertical "striping" you can see on Andy's. The patch was most likely removed to prevent any trademark issues, but keep in mind he's constantly wearing that duty belt, so I don't know you'd ever really be able to see it anyways.
I can upload pics of my black 514's compared with the new ones if you like. It was pretty easy to find the right jeans using pictures and comparing fits, as I'm 5'10" around 155 lbs, so if it was even close to fitting similar to Rick's I knew I was close.
The new 514's are far too baggy in the crotch and thighs, and the 513's look too tight at the ankle. 501's are about the right cut, but they don't make them in a zip fly or stretch denim, so I dug around to find a similar fit to 501's. Turns out the 514's were actually supposed to mimic the 501's with a zip fly, and being marketed and "slim straight" where now they're just labeled as being straight. If you try to find them on google you'll get 511's as the result, and those are WAY to skinny to be right.
So far I've been through three pairs of 514's from different years, with different denim mixes, and I already owned a pair of 511's to reference. Im pretty confident I've got *the* jeans found.
