Looks kinda like a bastich to me.
Just for reference an IEC motor (metric) frame number is based on the nominal dimension of the height of the shaft center from the foot mount in millimeters. In this case 4.225" x 25.4mm/in = 107.3mm. Standard frame sizes would be D100 and D112, take your pick. Shaft diameter for either of those is 28mm with an 8mm key.
If you go strictly by shaft size the D80 is closest with a 19mm shaft with a 6mm key.
If you go by rated output the standard frame for 1.5kw is D90. This is for a 50hz motor with an output speed of 1450rpm (1740rpm @ 60hz). A D90 uses a 24mm shaft with an 8mm key.
A NEMA 182/184T frame motor has a shaft height of 4.5" with a 1.125 diameter shaft with a .250 square key. Nominal horsepower for this size is 3hp for a 182T frame and 5hp for a 184T at 1800rpm. The only other difference on the 182/184T is the bolt hole spacing: 4.5" for the 182T and 5.5" for the 184T. Since most of the dimensions are the same, many of these have the feet drilled for both sets of holes and are dual frame marked.

Be careful what you wish for, you might just get it!
