Not so strange for B737 to be used for the B757 selection. Cirrus (who I know VERY well) use a Dash-8 SIM for the selection for their Do328, E170 AND B737 potential pilots. Cityjet use a B737-200 SIM to select the ARJ/BAe146 pilots, so it is not uncommon, although I suspect that that is more due to SIM slots at the overcrowded BAe146/ARJ sims!!!
I will PM you what I know of the T's and C's.
