BC127 SKU numbers and features

What is the BC127-1104323? Where do I find a list of SKUs and descriptions?
From a different post these SKUs are:
1103383 - Standard BC127 with 5.0 RC11 firmware.
1103709 - BC127 HD with firmware with 6.1.5 firmware and APTX HD.
I am a nu-bee, sorry if this is in the wrong topic or wrong forum.

SKU 1104323 → BC127 with MELODY 7.3

We don’t publish a list of SKU numbers with units and features, you need to ask your disti (who do have one) and they can as us if needs be. Its all too easy for customers to make a mistake but also for sales guys as the products are quite technical.
