Channeling T-Mar here - the presence of portacatena-tapped drive side drop out indicates 1978-1982, unless old stock was used at a later date.

And yes condition may not be good, but i why not put some effort in a nice restoration.
SL should have rifling in the head tube, and should be obvious. SLX will also have rifling in the seat tube, which can be seen/felt through the BB. The seller should be easily able to verify this, I would think.
EDIT TO ADD: For an Italian frame, I think an original braze-on FD tab would indicate a 1982 build at the earliest, unless it was added later and the frame repainted. If it's original, then you're looking at a bike from 1982 or maybe 1983, unless an older DS drop out was used.
