Yes, I'ts Bijur and they're still very much in business up in New Hampshire as I recall, but they ceased servicing the auto units some years back.
What you call check valves are actually metering valves with a filter (known as drip plugs), metering different amounts of oil depending on the specific location's requirement. For example, the clutch throwout bearing gets less oil than spring shackles. The lubricant used was Bijur Oil which is approximated today by either SAE-50W motor oil, or SAE-85 gear oil.
The Bijur system was a trademark feature of better cars of the era and I hope you change your mind and decide to restore it to operation. Frankly, removing 43 drip plugs and lines and drilling/tapping for as many Zerk fittings is probably more work than restoring the Bijur, not to mention the effort to get at them all with a grease gun every few hundred miles. Many Bijur parts are available from Classic & Exotic including the very special size tubing, and from Bruce Blevins for the drip plugs. I'm a bit of purist to say the least, but I know many share my view that a restoration that eliminates the Bijur degrades the value of the car, and is a sign of a lesser quality restoration.
Bijur plan from 7th series attached below, earlier series are similar. I've a bit of experience with the Bijur, PM me if you want more info. A Bijur manual is on this site and available for download.
