Distributor Identification?

I have this electronic distributor on my C-type replica, which has a 3.4 engine. Can anyone identify it so I might find specs on timing etc? Also there is a vacuum advance unit that is not hooked up to vacuum. My car has Weber carbs. Where would I pull vacuum if needed?

Thanks for the replies,

Mark, the shape of the pickup module looks like a Pertronix, not Accuspark or Powerspark. Are there no markings on the body at all?

Also the sticker on the module that say NV5M and the Lot # stuff is how some Pertronix are labeled.

That’s a Pertronix distributor, D177600 if it’s negative ground.

Ok thanks guys. It does look like it in the Pertronix catalog. I can look up info on it.
