Note the extra bracing of the top north of the soundhole and to either side: #1 and #2.
Both Embergher and CF Martin used this technique to help resist top deflection and neck rotation, though they both used slightly larger plates.
Note also in the interior splice (#3) across the joint of the two pieces of the top which continues to the neck side of the folded cant in the top: #4.
I am interested in why you think it is Sitka. I think it would be unusual that an Italian maker imported Sitka spruce in 1921. There was a good supply of spruce available in Italy. Also Sitka spruce was in high demand in the US for aircraft production.
I would like to use the original finish of the hole (rosette) but I need to fix it first. What are patterns embedded in? Is it enough to pour bone glue, polish up and varnish
Nevin,

I found an article describing the types of wood used to make mandolins. I do not know much about tree species and I did not know that Sitka spruce grows in Alaska ) A very valuable note Thank you
