I have a mandolin made by John Brandt with a date on it as 1899 which was made in chicago. It has 2 long cracks in it and I am trying to find out if it can be repaired and any recommendations. It was my grandfathers with his initials enlayed in the handle stock. I really do not know anything about mandolins as I do not play any instrument but this is the only thing I have of his and is a family airloom. If anyone has any information I would appreciate the help.
