Not really: Cinelli made the BB shell, and they sold thousands to hundreds of frame builders, at a glance the stay sockets look to be oriented like the model CCM, which was the later replacement for the SCM. Correct that the modern logo (assuming the shell has one) places that piece "after 1978" but otherwise no clue as to who the frame maker is. A 27.2 seatpost is a good sign (that the tubeset may be something like Columbus SL) but does not indicate a year "after 1983". More and better clues will be close-up and in-focus pix of the dropouts, the seat cluster and other lugs, that BB shell with serial number, the brake-bridge, plus what the threading is...but I'd bet on Italian at this point. I think I see a "spool-shaped" chainstay bridge another piece made by either Cinelli or GPM. I'd also say that unless somebody recognizes this Martin brand it probably will turn out to be one of hundreds of contract-built Italian frames made by one of the well-known but secretive big firms and possible shipped to a Benelux seller, if it had a "number tab" under the top tube that guess would be a dead cert!
