I wanted to update this thread for posterity's sake; I've researched this extensively in anticipation of replacing a panel in the 67 international.
From what i have researched it seems that the 'mahogany' used in the 67 international is 'Philippine Mahogany", which is not really a true mahogany. The Wood that can be called "Philippine Mahogany" or Lauan / Luan, is also known as Meranti, all come from southeast Asia, and used to be made of wood from the Lauan tree.
Today what we think of as 'Luan' (cheap, thin tropical hardwood plywood) is really a different species than what is was in '67, no longer coming from Philippines
. Most true Phillipine Lauan
is totally gone and now unavailable due to deforestation. What we are really getting when we ask for Luan is a muti-species product that is not really from true "Lauan" trees, but instead from multiple species from Malaysia and other SE Asia countries.
So, I picked up some of the red 'luan' and will try to match the finish with stain (restore-a-finish , mahogany flavor). Seems to be the best / only option. Hope someone finds this useful in the future.
