Portland & Rochester #1 "Presumpscot"

I just found a group of negatives of which this is the first. It shows
Portland & Rochester #1 'Presumpscot'. Fortunately is is dated, but, there is no location.
Can anyone help with the location?
Thanks,
LS

a friend at work, who has published a very similar picture (different locomotive, same consist, different snow cover)
says he has seen two copies, one marked Peabody, the other Westbrook. If it is a P&R loco, Westbrook is much
more likely as, motive power, in those days, stayed on the home line. Of course, the engine became a B&M
engine but, was renumbered.
