Yellow 1 was an A7...yes?
The fact that it has the straight-canopy, not the blown canopy suggests that it probably was an A8, even though there were A8s and D9s with the older-style straight canopy. Having said that, the difference between the A7 and A8 is minimal enough to warrant its inclusion as an A8. There is at least one A5 that was actually an A4 and the difference between those two models was significantly more substantial.
Fencer is correct, though, the A8 list is soon to be full and the list is currently populated with a relatively high quality batch of skins. A couple of the earlier ones with some garrish colours could do with replacing, perhaps, if some better ones were submitted.
I am currently working on this one:

It's about 70% done, all of the tedious and boring rubbish is done... Research, mapping out correct rivet patterns etc. I'm just finalising colours (I think that the RLM 74/75 mix on my 190A5 skin is too light compared with the the RLM 76, so I'm trying to find a good balance) and working through the individual parts of the skin.
It should not be too far away and hopefully will be my best one yet.
