Power Prop Gliders - Introduction

This is my collection of Power Prop Gliders which happen come in red & blue bags.  This collection is different from the Power Prop Gliders which come in the red & yellow bags.  I am not sure whether the red & blue bag set is older than the red & yellow bag set, or vice versa.

This collection is confusing to me because some of the gliders are labeled as being made in Japan, other in China and others in Taiwan.  One glider came in a white bag.  Some appear to be of much higher quality and detail than others.  There also appears to be 3 different sets of 12 as shown on the reverse side of the packages.

I put the number of each glider that I own in ( )'s.  I am missing the YAK Type 2 and a whole bunch of the third set shown at the bottom. I consider the first 2 sets listed to be identical other than #9.

One set is shown as:
1. Hawker Hurricane (1)
2. Messerschmitt BF109E (2)
3. Grumman F6F Hellcat (2)
4. Supermarine Spitfire MK. II (3)
5. Type 4 Fighter Hayate (2)
6. Type Zero Carrier Fighter (4)
7. Focke Wulf FW190 (2)
8. Republic P-47 Thunderbolt (1)
9. YAK Type 2
10. North American P-51 Mustang (2)
11. Type 3 Fighter Hien (2)
12. Lockheed P-38 (1)
(For some reason the P-38 is shown as #13 and the Type Zero Carrier Fighter is shown as #6 and #12??)
