EE 1005 construction diagrams

I have scans of two different versions of the diagrams for this kit, one unnumbered and one marked as version 3. There are five categories of differences:

1. In C4 and C5, a 10 Ω resistor is added in series with the 10.000 pF capacitor connecting the leftmost transistor to the white oscillator coil. The corresponding change is made to the schematics in the instruction manual between 1968 and the 1969 versions.
2. Icons have been added to the front panel terminal connections.
3. Some mounting springs have been moved to avoid the risk of components having too short connection leads to reach them.
4. Some insulated wires are drawn further away from springs they do not connect to, in order to avoid ambiguity if they get interrupted by the punched holes if these are slightly offset from the center of the springs.
5. In C6, E13 and F2, serious errors had been introduced; some EE 1005 and EE 1000 kits included a correction sheet rectifying these.

If the set without a version number is version 1 as seems most likely, it is not certain which of these were also present in version 2. My guess based on the dating of the presumed version 1 set is that version 2 was created specifically to include the added resistors. I find it unlikely that it introduced the errors, as one would then expect them to be corrected in version 3. Those errors were in turn most likely introduced with the movement of springs and wires, which would then not have been present in version 2. The front panel terminal connection icons could have been added in either of the two revisions.
