This is middle stone paint?

Brake lines added by consulting ref pics...

Looks like Monogram got the gear supporting links wrong, (they are molded pointing backwards, whereas they should point towards the centerline). I removed them, to be attached at the correct angle at later stages.
Thanks for stopping by!

Thanks my friend @johnb! P-40 landing gear retracts backwards, not by a retracting link (as one might imagine by studying the Monogram rendition), but with a distinctive gear mechanism that retracts and simultaneously twists the leg.

In theory, the P-40 landing gear would be more prone to jamming, since it would perform two actions (retraction and twisting), but have no info on it, my friend @eb801

Surely, it was more prone to collapsing than contemporary designs. I found the following very intetesting text in Wikipedia:

Pilots used to British fighters sometimes found it difficult to adapt to the P-40's rear-folding landing gear, which was more prone to collapse than the lateral-folding landing gear of the Hawker Hurricane or Supermarine Spitfire. In contrast to the "three-point landing" commonly employed with British types, P-40 pilots were obliged to use a "wheels landing": a longer, low angle approach that touched down on the main wheels first.

Yep, Wiki, as well as many Net merits are wonderful partners, my friend @eb801! Especially for us modelers who want to know info about the subjects we model.
Hopefully tonight (kids permitting 🙂 ) I will freehand the dark green.

Nice work on the freehanded dark green, Spiros @fiveten

This and that...

The seat had an unrealistic hole at the rear, which was blanked with sheet styrene... Sheet styrene was also used to blank the emptiness behind the seat and look like a bulkhead-ish... Basic cockpit color applied... The front "bays" area was painted yellow zinc... Exhausts and guns were painted gun metal. The wheel covers had their fancy decals applied. Decals worked well, apart from the fact that their glue has aged to a yellow shade. Luckily it will not show onto the model... Thanks for stopping by!
