Interesting. The stem is just so-so, but we have never seen that double cable guide before. Looks nice.
Seller’s ad copy is curious, however (“while it appears structurally solid, this part is sold for display purposes only and should not be used”). Someone wishing to avoid litigation, perhaps?
from a 50s era race bike, 100mm extension, 22.0 mm quill as measured with my micrmeter, nutted handlebar binder, the stem is in nice shape with no gouges or significant scratches, the red fill in the “cutouts” is in good shape. Includes a cool TA brake cable housing guide with rubber grommets.
