Looks like aftermarket. With lots of rust.
 
Sure does not look stock..... maybe a crude attempt at proportioning with a variable flow restrictor in the front system.....very odd.
 
yes just wondering,I wont be putting it back during the restoration thanks
 
Not OEM. I would be concerned about how rusty the brake tubing is
 
yes all brake lines will be replaced during restoration thanks
 
Ditto above. 1971 would have had a "combination valve", meaning proportioning - imbalance switch - metering valve all in one device. That appears too small to be a prop valve and is also on the front circuit, so probably just a needle valve as a flow restrictor. Why is the main question and "looks scary" seems a valid response. Seems in Canada you run into hillbilly fixes too.
 
That has compression fittings, my understanding is that they are illegal in automotive brake lines. Definitely not factory. I would guess it is someone's way of locking out the rear brakes so that they can do burn outs. A poor man's line lock.......

Good eye. That piece may be some sort of needle valve, never designed for a brake system

But that is on the front brake lines!

Brass are illegal steel compression unions are not.
I looked all that up when I put my line lock in.
 
TrailBeast, I am a criminal. Long ago when a rusted tube twisted off on my 69 Dart at a front wheel cylinder, I "fixed her" by installing a section of tube w/ brass compression fittings. The cheap plumbing type w/ 1 brass ferrule instead of better Swagelock. Car was stolen much later, so can only dream it failed when the thief was running from cops. They did arrest a guy in a stolen Jetta w/ my license tag 7 yrs later.
