Dating Ludwig Drum products can be rather easy or quite tedious.
In reality, the early days of drum manufacturing held no regard for dating or serializing a product for chronological relevance.
The interior of the shell was clear in 1960, and by 1961 all shells were white up until 1967.
By then, the shell mold changed from using a mix of mahogany and poplar to using maple and poplar in the same style 3-ply mold.
In fact, it wasn’t until 1964 that Ludwig started to put serial numbers on their products.
