oh i come too late ...
I saw tyour post yesterday but had no time to answer...
I my opinion you didn't have to take the Eduard prop as reference it is totaly not acurate..
first one was much better.
The prop you did was teh "Levasseur type 484" which equiped most of the ni-17.....


here are the real size (not very important for us...)
be carefull dran proportion are not accurate, only numbers are...

here you have a Levasseur type 586 (all Levasseur had same form)


so I think first prop you did was much better.
Second about wooden effect. your wooden prop are really amazing , but in french case props were covered with "gomme laque" first , then "Tonkylaque" since 1917/18
"Laque" means enamel in french...
it is between varnish and paint.
What I mean is that french props had very dark red brown apparence. and no wood effect was seen.
her some exemples, but i can show you more autochrome ...



here is what i did in a morane and in a ni-11...



if you are interest, to learn this effect i use a sand yellow base, the, i mix Prince august "woood grain" (70828) with tamiya red clear and pas several coats with pencil.
I am sorry all this come too late but anyway as you are represebting a replica, all is free prop have not to be accurate...
by the way could you please detalled step by step how did you do the prop? (kind od wood instrument to sant, haw do you cut and so...
they are the pretiest wooden rpops i never saw at 1/48.
Congratulations for the all work
