greetings from Mad Scientist Guitar ....I have a 1938 Cromwell on my bench at the moment, fixing a neck heel crack that will require some color matching to re'stain .....in an effort to get my color shade just right, I'd like to do my test swipes on the same exact wood that this neck is constructed from ....anybody happen to know, definitively, what wood the Kalamazoo factory utilized in 1938 for these Cromwell necks ? ....this would be a huge assist in getting the stain color just right .....THANK YOU for your help, be safe -
