26 x 1 3/8. The other is 26 x 1.75, smaller.

probably 26 x 1 & 3/8" to fit an EA3 rim. The serrated rims are typically a European make (Rigida). Those serrated rims were most often used on French bikes in the 1960s & 1970s but Rigida would sell to bike companies anywhere. I have a 20" bike with serrated rims so they were made in many sizes. The serrations were supposed to help in wet weather braking.

When you say "26 inch", that's just a broad category. There are at least 10 incompatible "26 inch" rim sizes with corresponding tire sizes.

26 x 1 aka 650 C for tri-geeks often labeled 650x23 or 650x25
26 x 1 1/8 same as 26 x 1"
26 x 1 1/4 aka 650B wider tires for old european touring bikes or the latest fad in mtb racing
26 x 1 3/8 S-6 Schwinn's own Lightweight size
26 x 1 3/8 E.A.3 for British 3 speeds
26 x 1 3/8 french aka 650A
26 x 1 1/2
26 x 1 3/4 S-7 Schwinn's own size for Middleweights
26 x n.nnn (any decimal size) all modern USA mtb sizes and Schwinn Ballooners (26x2.125")

Somewhere is an EA1 size too.
and some really old odd usa 26x1.25 and 26x1.375 that are fit a different size from modern usa decimal mtb tires.

Oh yeah, don't forget the new FAT tires. Most are "26 inch" but are far too wide and have their own extra wide rims.
Fat like 26 x 3.5 or 26x3.9 or 26x4 or 26x4.5
