Matt,Oh man, I am sorry. I did not realize you were on the interior.
The interior is being updated on the 156 side and that will be moved to the 51 today.
The only wood mentioned in the articles is on the floor.
I am thinking a darker inlaid wood in the aisle that may be covered under the seats with carpet.
The overall aura should be one of elegance, expensive decor, and comfortable. Leather seating would be preferred of a dark red, maybe wine colored.
The walls were doubled and enclosed for sound deadening, and there would be shelving under the windows. See the work I have done on the 156.The shelving may be dark cherry or a color matching the leather seating.
I would expect fine metal and/or wood trim along the walls and windows and around the doors.
To quote an earlier post:
"From what I have read, great hopes went into these aircraft.
Each were hand-built with great attention to detail.
I agree that the intended clientele were wealthy travelers and this would be reflected in the interior appointments.
My guess on the passenger cabin is based on the description of the flooring, and the assumption that Czech decor of the period was conservative and somewhat muted.
For the floor, walnut may have been chosen for it's durability and lighter weight than other hardwoods. Since it was inlaid, some of the aluminum floor structure would be visible. The wood may have extended up the sides of the cabin wall a foot or so to prevent scuffing. The airline would have specified leather seating for durability. Rather than black, they may have had a dark oxblood finish.
The fore and aft bulkhads would also have been leather padded to protect passengers in turbulent weather.
Lever type door latches would be recessed.
A dome light or two would provide general lighting, with a separate lamp for each seat.
Cabin windows would be provided with opaque shades or curtains."I do not see curtains in the pictures so I have not added them.I can send an "Interior-only" model if that would help you to see things better.Here were some of my earlier thoughts for added confusion
For interior design, my thoughts are:
1) General wall colors are light (not white) but something that would go with the exterior, maybe with some texture
2) Cabin Seating is leather, maybe dark red or wine, very dark.
3) Side panels (shelf) I would prefer something dark and elegant, not fancy, sides can be a mixture of seat leather and wall texture? and some kind of interface border to tie them together, metal, wood, etc. Top shelf has to be durable, can be a matching dark stained wood, or something that might match your interface scheme.
4) Floor should be a dark inlaid wood, maybe stained dark brown or cherry if you use mahoghany, can be floor wide, or some subtle carpet under the seats.
5) Window treatment: some kind of window framing would be appropriate, just keep it subtle.6) Shadows and shading in all corners and recessed edges, under seating, both sides of wall, floor, panel interfaces.
Area above windows gradiently darker than sides, Flooring should be shadowed down, very dark under seating.
Side panel recesses (holding newspapers) should be darker.
Generally I prefer subtlety, not clear distinct detail.
This is just a sense of my thinking. If you have ideas about a different approach, feel free to share and let's do it.
I have attached a color swatch that I used on the 51 for testing.
Colors similar to these would match the exterior well.
I really like the wood and metal and cloth treatment we did for the Spartan interior:
