This is 1/72 DFM, they come in two pieces, you can detached wings from fuselage and you will find matching serial numbers. Yours is one piece, do you see any mark on the belly ?
You can unscrew the stand and look for any mark.
Thanks all for the input. From what I can see on the Mercator, mine is very similar but slightly different. Mine has fluted corrugated exhaust nozzles, it has a "lightning bolt" style red stripe down the side and lightning bolt decals on the engines, and the livery font is different. Possibly just a different year or variant?
