Need help with oil tank identification

[Luislang]

The oil tank on my barn find 911 restoration has two additional ports (behind 34,33 in the picture) to connect oil lines. I'd be most grateful for your help to:
1. Identify the origin of the tank (which model had it installed)
2. What gets connected to the two ports.
These have been pinched shut and soldered closed on my tank.
Thank you in advance for your time!

Sportomatic outlet hose.

Thanks pors1968-would one be oil inlet, other oil outlet? ..... And how did Sportomatic box use oil?
Can I use these for turbo oil supply?
Thanks!

It could be a turbo oil tank if your tank look like the one you show but if you have a pict i can check i have both in my stock .

I'll have to remove to photograph. Thank you for your offer!

I'll have the same oil tank in my 1969 sporto.
the extra connections go to the torque converter housing
