Super-O Operating Track Set No. 39 was included in Super-O sets and contained all of the small items that were needed to operate these sets. The contents varied depending on the requirements of the sets. The envelopes that contained these parts were issued under a number of different identities.
These included No. 39-5, No. 39-10, and No. 39-25 which is pictured to the right. Below we’ve pictured envelope No. 39-3. Note the "X" suffix that is stamped on the envelope next to the number "39." The "X" indicates that this envelope was included in a Super-O set.
Produced from 1957 until 1966, it is the envelope that is the collectible item. The values of these envelopes vary according to the contents and the condition of the envelope. |
