If you're talking about the old ones, they were made around the 40's and are a dead ringer for the Kay mandolins made at the time. I strongly suspect they were made by Kay. They seem to have decent wood and are built well enough. I have a Kay that's held up fine considering its been around for more than fifty years. There is no truss rod and this one apparantly suffered some in a hot trunk at some point in its life. The glue in the heel joint softened and then hardened so it pulled out a bit. The neck had a bit of a warp too. I took some time and scraped out the glue and reset the heel. Removing the fingerboard and planing it flat took care of that problem. It's been holding up fine. A good mandolin when the old Gibsons can't be had.
