What brand booster is this?

Hey guys,

What brand booster is this?

I got this with a 71 duster. The car was converted to 73 brakes
does this look like the right booster?

Thanks

It has a mopar sticker on it.

That is correct for 73 up ....72 and earlier were flatter and bigger diameter....they actually look like dinner plate size

I pulled one that looked identical off a 73 or 74 Dart (actually a bit rustier). It is a Midland-Ross booster. The V-band makes it simple to take apart. I also had one on my 65 Newport, but it was a rebuilt, and the firewall bolt pattern differs. The alternate is a Bendix(?) model, with the 2 shells crimped together. My 65 one had a hole in the diaphragm where the vacuum enters, despite using a filter to stop gas fumes. I looked everywhere for internal parts to rebuild it, but nada. Finally made my own diaphragm from neoprene sheet, which tested OK but haven't run it.
