Campagnolo Nuovo/Record Bottom Bracket Spindle too Short

I bought what I thought to be a Campagnolo Nuovo Record bottom bracket. When it was installed, the spindle appears too short and is loose in the bottom bracket even though the length matches what is on Velobase.com. I searched and found that there were both thin walled and thick walled cups on these bottom brackets. I am thinking I may have thin walled cups with a regular spindle? Below are the specs and pics. I'd like to make sure what I need before I try and replace the cups.

68 mm bottom bracket
Spindle marked 68-SS-120; 112 mm; 51 mm between the bearing races
Campagnolo Nuovo Record crankset with 11 in a square, which Velobase says takes a 112 mm spindle

If there is anything else needed to make a determination, let me know. Here are the pics. I should have taken a pic of the bearings, but there are 11 bearings in a race. That also matches Velobase for the bottom bracket. There is also a 14 bearing 3/16" race for the thin walled bottom bracket on Velobase.

These are indoor pics, one with a flash and one without.

Yes, those are thin (un-r!fled) cups. And your crank is post cpsc (1978), so should take a 114.5 mm spindle. You may need a whole new unit. I may be interested in a straight swap for what you've got. I am 99% sure I have a 114.5/thick cup 68 English BB in my stash.

Here's my cheat sheet:

Italian 70mm BB:
Double -Pre CPSC: 113mm. Post: 115.5mm
Triple - Pre: 118mm. Post: 124mm

English/French 68mm BB:
Double - Pre: 112. Post: 114.5
Triple - Pre:117. Post: 123

Spc -- ≻ c - record
Ssa -- ≻ croce d'aune
Ssb -- ≻ chorus
Ssg -- ≻ athena

That is helpful. I do have another crankset without a date, which puts it early 1970s, I believe. Now that you mention it, that crankset was purchased at the same time from the same person as the bottom bracket. I grabbed the other crankset because it had the chainrings I wanted (52-42 vs 52-48), but I can just swap those. The crankset without the date code would need a 112 mm spindle, correct?

Those are markings for later 80s/90's BBs.

the rifled NR cups had to be thicker, to put in that grit shedding spiral, so axle inner races were closer together.

without the thickness for the spiral the cups, thinner, axle races further apart..

68 - ss- 120 is from 5 speed era.
