Here's a very rare Clear French Radio Strain marked "SIFOR" [front] "Depose" [reverse]. It may be hard to see but the marking is over blot-out letters! Best guess is this was a Pyrex mold that was blotted out! Only one known to date!

Has 1/2 pinky nail and a matchhead flakes on one rib, otherwise VNM+! Don't snooze on this one! First email gets it for $150 postpaid. Thanks!
