The problem with Lancs is that, as far as I can tell, all in Bomber Command were painted exactly alike: green and brown on top and black everywhere else. No variations in camo colors over time, like with Brit fighters. I think the Lancs all even used the same pattern for the camo, unlike the mirroring sometimes seen on Brit fighters. The only differences were unit codes and nose art, although sometimes they put different colors on the fins as your pics show. So nobody's ever thought it worth the time to make a whole huge buff skin, with the only difference from the stock skin being the lettering and serial number.
That said, Coastal Command used A FEW Lancs, and that was a totally different scheme. You know, green and gray on top and white elsewhere. That would be worth doing. However, I've scoured the web for hours looking for a CC paintjob for a Lanc, and have come up empty. Even on the CC official page, they mention they used Lancs but have pics from BC. The only thing I've found is a pic of a die-cast model with the CC paintjob, which I didn't consider worthy of using as a source. The problem seems to be that CC had so few Lancs (1 squadron tops, IIRC, for a limited time). It wasn't a big enough deal to get documented thoroughly.
I suppose someday I'll try to do a B24 and/or B17 in CC colors (plenty of documentation for that), if somebody doesn't beat me to it, but it's a low priority.
