I just bought a New Royal treadle at Goodwill. Its a complete machine with 2 bobbins and one bobbin case. It also came with a complete set of hemmer feet in the original New Royal tin. I found only one needle. It was installed in the machine so at least I know witch way the eye should face. From what I have read online it takes a Boye #4 needle for New Royal Vibrating Shuttle.

The key with older unknown stuff is to be patient and observant.
Gently try each shuttle with the bobbins to see what fits what.
Pair them up and zip lock bag them for future reference(my method)
Then try each shuttle in the carrier and cycle the machine gently.
Watch for how much "slop" or "rattle" they have. it should be very clear quickly which is correct.
The nice thing about older machines is the threading is usually self explanatory.
Rule one:
The bobbin goes into the shuttle so that the thread makes a direction change as it enters the slot (usually at an angle on the edge)
Rule two:
The thread has to pass through a tension on the shuttle before it is picked up
Rule three:
Threading the top path is generally some variant of
Spool, guide, tension, guide, take-up, guide, needle
Rule four:
The side of the needle with no groove must face the hook when lowered
Rule five:
The needle thread direction is generally from the no-groove side to the groove side
For Needle choice:
In reality any needle that is of the correct general type (curved or straight) and long enough can be made to work.
Step 1: Move unit until the needlebar is all the way down.
Step 2: Continue movement until the needlebar has lifted approx 3/32 of an inch
Step 3: Set needle in correct direction and height so that the eye of the needle is 1/16 inch below the point of the sewing hook.
This can get most machines sewing....

Boye #24 is New Royal 20x1. #4 is New Home 20x1 but close enough to work. The later New Royals used 15x1. Boye #24 measures 1-13/16" in length and #4 is a smidge shorter. The flat side of the needle shank should face to the right.
