Can any of you reps at RN tell us more about Proline? Is this a new brand/OEM mfr, a subsidiary of Allmakes, Bearmach, or what?

I just installed a Proline brake booster courtesy of our hosts. It's a nice unit.

Finally, any info on Series NLA parts that are being reproduced in the future? Not looking for anything specific, just curious if we will have to continue to scavenge or if there's hope for new supplies of now NLA stuff.
