Shimano Aero AX Frame Serial Number Verification

[vibe9292]

Hi All, recently I chanced upon this size 54 frameset & was immediately attracted to it, but I would like to verify whether is this a real Aero AX frameset produced by Tange for Shimano in the 1980’s, serial number is M2D11200.

Any info input will be very much appreciated. Cheers!
