There is an '81' date stamp on the locknuts. Thanks for suggesting that! I'm sorry about the picture quality; I'll try to get better ones later today. As for the rims, there isn't much to go on. They have red oval stickers that say:
Code:
AL 320
RIGIDA
Made in France
They're narrow with what I believe to be single eyelets (I haven't taken the rim tape off). They're definitely a bit the worse for wear, but for all that entirely useable.
If they are indeed Tipo hubs, what level would that be? Middlin'? Low middlin'? High middlin'? Inquiring minds wish to know!
