Perfectly classic and works great; Firmware Version: 2.0-20100601

Anyone using these HC-05 modules knows that there are many different hardware and firmware implementations and not all work the same. I don't have any special requirements for this BT module but I use it with Arduino and AT commands and set AT+NAME, AT+UART and AT+PSWD. Also I need some data buffering and blocking when the buffer is full and I had problems with firmware versions 3.0 and especially 4.0. For this device from DSD Tech firmware version: 2.0-20100601. That works great. It's marketed as a Classic, and it works great that way.
