Could be up to a few hundred volts on the 45CT1.
According to this post, http://photo.net/bboard/q-and-a-fetch-msg?msg_id=00JlFD , they say serial numbers below 534,000 are high voltage.
You can always measure it with a meter - across the outer shoe and middle pin (but DON'T TOUCH with your fingers

I second that.
The other day I got a painful jolt off my Dad's little Braun 260 BC (very basic, also pretty old - hence the 'BC', I guess) in the process of measuring its trigger voltage that turned out to be 210V.
Of course, holding the probes one in each hand.

In retrospect, it was a bit of a case of "well duh"!
