or are they two unique and different instruments (both Mango) as what appears by the virtue of different serial numbers on the sticker inside the sound hole?
Do you have children for whom these were originally gifts that demand to have the SAME as their sibling does? (ha ha, speaking from experience)
One is a soprano, one is a concert. That they were both the same color was coincidence. If you also take time to look at the pictures I posted you'll see there are differences and why.
