Then it might be ok for your dataset, however it doesn't look like anything
standard.  Do you notice a 150m shift between the dataset and other data (cf.
datum transformation)?

And the possible datum shift.

There's just a difference of 60km between the y-coordinates. :)
So the projection you've been given seems to be the right one for the dataset,
even though it's not any one I know of.
