Help identifying dead electro. cap polarity?

This cap was removed from a 70's-80's German industrial machine:

<http://i37.tinypic.com/10psxg3.jpg>

It has no polarity markings. One terminal is common with the metal case. Is
this always an indication of the (-) terminal?

The base has molded terminal locations numbered 1-4, two of which are empty:

<http://i36.tinypic.com/e6x542.jpg>

Markings on the side are:

B41111-B7108-T
1000uF 40V-
GERMANY
GPF DIN 41332 06.78

I find a few references to a Siemens part that is similar:

<http://www.screenghost.com/shop/show.asp?ID=74#>

but no datasheet can I find. Can someone more resourceful than I find one?

I cut open one of these caps. It is paper & foil (or so it seems) spiral wrap
construction. Can polarity be determined by internal construction? Is the
center terminal always one pole (ie, always +)?

Thanks.

The usual cause applies ?????

FYI:

The markings are clearly 1, 2 and 3 with the fourth a NEGATIVE sign
!!!!!!!!!!!!!

Is not the negative sign *right next* to the pin linked to the case ?????

To me they look like "1" (not a "-"), "2", "3", and a really weird "4".

But with your help along with the one pin (yes, it's the (-) one) in common
with the case pretty much confirms polarity.

Thanks!

Nighty-night! Lights out!

Are they? Their order is a bit strange if so.

On the other hand, take the - to be a 1, and the other symbol to be a 4
with a bit missing, and you have 1, 2, 3 and 4 in a normal order. So the
situation is far from clear enough to form a basis for installing a
replacement.

** Nonsense.

The stroke on the " 1" has been made longer to avoid confusion with the
" - " sign.

AFAIK Germans always write a ONE with a tag ( opposite 2) and a 7 with a tag

through it that makes it look like a lower case t.
So I suggest the - really is MINUS.

Almost always, but ISTR reading warnings that occasionally you come
across one made for use with a negative supply rail, when the can will
be positive, so you're right to make sure.

However, in this instance I agree with other posters that the markings
indicate that the can is negative.

Me, I'd guess the terminal marked with the '-' is negative, but that's
just my warped thinking.

I don't set a 4 or part of one. Yes the number pattern seems non
conventional but what is conventional in electronics?

Ahh but it's german. They make the 1 with that little hat. And then
when they make a 7 they always add a cross through the middle... so as
not to confuse it with the one.

This is how right-pondians write the numeral "1". They also cross their
"7"s. ;-)

How is it wired in the circuit? When in doubt, this is what I look at.
You can also substitute it with an AC rated cap and just measure the
voltage across it to find out which way around it should be.
