Default Magnetic compass polarity reversal??

Hi,

I'm looking at relocating my satellite dish next weekend.

Just got out my trusty 30 year old SILVA compass to do a bit of surveying,
and I've noticed the red (should be north) end of the needle is pointing
south!!

By way of confirmation the needle still "dips" to the north...it's just the
wrong end of the needle that is both pointing and "dipping" to the north.

Can anybody offer a plausible explanation for this? I'm mystified!
