[Milsurplus] Instructorgraph Tapes for Sale

[Keith Densmore]

Greetings,
Any Instructograph owners out there?
I found some Instructograph Continental code  tapes in the dungeon.
They all come with their boxes and as far as I can tell can only be 
identified by the number on the box. Some of the boxes show their age, but 
the paper tapes appear good. One of each except as noted.

No 4
No 5
No 7  (two of these)
No. 9
No 10 (no box lid)
No 12
No. 18

I really have no idea of their value, so how about your offer either for 
singles or the lot.

Thanks, 73,
