O.L.D. On Vintage Schwinn Question
New to this so I’m trying to understand what is obvious to everyone else I guess. 1979 letour IV. Made in Chicago frame - by serial no and small code stamped into head badge plus decals etc. With the rear wheel removed the width between dropouts is 122mm. However OLD on rear hub which definitely appears original is 125mm. Others have said this should be 120. Looking to upgrade/replace hub due to lack of parts and assume going one mm wider to 126 would not be a problem since frame will flex that much I assume. Know that swapping different locknuts and washers in hub can change things but I really think this thing is original. Does anyone have comment or info that would help explain

If it was originally a 6-speed, 126mm is probably correct. Many Schwinn 5-speeds used 126, as well, because they had a chain overshift guard outboard of the small cog. At any rate, spreading a vintage steel frame from 120mm to 126mm or even 128mm is no big deal -- been there ... done that on several occasions.

1979 Schwinn LeTour IV was a high tensile steel, 27-inch wheeled, 10-speed bicycle. So, you would be looking at a 5-speed freewheel according to the catalog. So, generally, these would have had approximately 120 mm O.L.D. But anything's possible.
Even what appears to be an original wheel may have been modified by a previous owner. Add 2mm of spacers on either side and (theoretically) one wouldn't have even needed to re-dish the wheel.

Yes it was a 10 speed. I owned this same bike back in the day. It’s all original but obviously hubs could have been serviced although the parts right down to slotted axle and matching washers are all there.

I guess I should say axle and related parts appear original. Although I thought I read somewhere that the OLD on these hubs were 125 which is exactly what mine measures.

120 vs 122 -
for decades all rear Maillard produced road hubs came with a 120mm OLD
did not matter if badged as Atom, Normandy Sport, Normandy Luxe Competition, Milremo, Schwinn approved, etc.
beginning about 1972 this dimension changed from 120mm to 122mm
the change permits greater clearance for the small cog
