BA9S is the socket base style - "miniature bayonet" in this case. 
T10X28MM is normally the filament style and length of the glass bulb, 
however a #44/47 bulb is a T3-1/4 size - I do not know what a T10 refers 
to in size without my books (and they are at the shop). Perhaps Ron can 
check that in his?
