D-9's are a pain in the arse, big time! Christ knows why I choose to make them my primary topic.. Then again, virtually NOTHING is definitively provable about them, so you can really go to town on the research and make up your own mind (like i think Japo and EE and etc, get the lower wings of 211164 wrong!) - makes life interesting! Regarding wings, there seems to be a 'mix' of undersides styles within sub-blocks, so unless you have a definitive reference, you can pretty much pick your favourite out of the styles used within the block. The W2 type seems to be the most popular after the first block; take your pick between RLM76 (or the variant shades), RLM75 or RLM83... There is even evidence of RLM81 at times! hahaha
Canopies; there is definately a theorised 'line in the sand', after which the fitting of the 'Galland Hood' (Blown) seemingly became standard on the production a/c - however, there are SO many cases of replacements (Flat replaced with Blown, Blown replaced with flat - there is even evidence that a Ta 152H flew with a 'early' style flat canopy) that this too, is only a guide!
Then there is the case of overhauled a/c, that because of the overhauling (or large scale repair), break all the rules regarding camoflage colours/patterns of their particular block... THAT really makes life hard! prime example is 601088, which ends up looking nothing like a 601xxx series a/c, even down to the fact it appears to have had a wing set replaced, with an A-series wing set!
Spinner - I'd inclined to go something between 1. and 2.; 1. looks too thin for typical JG 301 (and was probably a transferred a/c), while 2. seems too thick at the base of the spiral. Again, if in doubt, a) see the 'typical' Jagdgeschwader style or b) see regulations!
