After sending my first post, I tried Google; I don't know about the size, but I think this is close - jump to end to see name of current mfgr, and by all means let me know if this is what you were looking for:
"A Source for Hard to Find Lids
Phyllis Flanigan asked where her client could find #63 canningjar lids for "jelly jars." These jelly jars are actually referred to as "table jars." Manufactured by Ball and sold in the 1950's, the jars have a quilted pattern, slightly tapered opening, and hold slightly less than 1/2 pint.
Number 63 jar lids (and rings) can be ordered through the
"Gardener's Kitchen," P.O. Box 412, Dept. 90; Farmingham, CT
06034. Ten dozen #63 lids cost $11.50, postage paid. Two dozen #63 lids and rings cost $8.25. ppd. The Gardener's Kitchen also sells standard and widemouth jar lids and rings, and canning labels.
Lids are produced by the Bristol Flowde Gasket Co., Waterbury CT.
