Good to see that you support my hunch, Richie, and with fancy words like 'protruding lip' as well. 😄
Thanks Ken! There's some more detailing on the way...
Strange isn't it, Rick?! There's actually no painting reference at all for the front side in the WNW instructions.
But, all in all I think I'll go for metal instead of wood. There doesn't seem to be a point in having that recess if both areas were wood anyway.
