The Santa Cruz OM Prewar honors its pre-WWII predecessors.
The Orchestra model acoustic guitar dates back to 1929, when C.F Martin started making them due to a client's request. Soon after the OM became the acoustic guitar everyone uses. Santa Cruz designed the OM/PW (Prewar) after those pre-WWII rare guitars with an advanced X and scalloped top bracing. The results is a louder and fuller sounding guitar. You will not find fancy rare woods or ornaments on the OM Prewar as it is not that kind of a guitar. Santa Cruz went after authenticity and kept the OM Prewar simple and stunning.
