Can someone help me ID this Redline? It says Trimoly. Stamped Redline. Serial is L90022105.

I'm trying to find out what mine is too

same frame with serial number L88041562

...i don't know anything about the serial numbers...but i've got the one here and it's ACR3k0531. Tri moly but my serial number runs along the edge of the bottom bracket were the cups go in. Mine has RL 440 stickers on it???

its a 90 model, probably a RL 320 or whatever they were

tri-moly, its a 440, hi ten steel would be the 340. chrome rear end and chromoly would be proline, i don't think that purple color was availble on the 540.

i knew it was something like that, lol
