The VINs for an MC28SP Rothman is between MC28-1000001 to MC28-1006013. I have no idea how accurate that range is. One way would be to check the color code. Under the real cowl, on the subframe near the rear pegs, should be a sticker with the original color code of the bike. That's at least some place to start. You might also want to post up more detailed pics of the bike to help with identification.

However, if the VIN ranges are accurate on the page I linked above your VIN fits in the 1994-1995 MC28 SE range.
