This is typical wooden racquet.
Back in the 60's that was the majority of my stringing.
I hope this helps! Jim
General wooden pattern: Pattern: 18 × 20 or 21
Tension range: 45-60
Start mains @: H
Tie off mains @: 6T
Mains skip: 9T
Start crosses @: 7H
Last cross @: 7T
Tie off crosses @: 6H, 5T
Shared Holes: 7T, 8T, 10T & 7H, 8H, 10H may be others but will be similar depending on racquet.
Be sure to place leather pads under 1 main strings, as this kept the string going straighter into the opening. If you do not have these pads, then just cut an old leather belt, as you only need a small pad to placed one on each side on the 1st loop on outside frame on 1st main strings left and right.
Many wooden racquets share a common stringing method. Others can be strung with variations on this method, like the Tad skipping 9H as well as 9T, but you can see variations with these racquets by the grooves in the racquet.
If you want to string as one piece then, Zig-zag (5 hole) groove will accommodate short side.These grooves are not standardized, so you may need to pre string loosly with some to determine the proper short side.I always strung them as 2 piece, especially with gut, as Bow Brand back then came in 2- 17' pieces to one set of strings.
You would start crosses on opposite zig zag side for 2 piece.There is like a double width groove that the crosses start from, the starting knot on one end of the groove and start crosses on that other end of the double width groove , as that is a shared hole with the main strings, this is the 1st of a few shared holes, so the crosses start off of this double wide groove that accommodates 2 string loops on outside of frame.
If you use a starting knot, with a wooden racquet it does not need to be a bulky knot as any knot used will not pull through the wooden racquet hole like todays grommet racquets would.
Back in the day, there were very few patterns as most wooden racquets were very similar with a few variances along the way, then came the T2000's and then others.
