Can you help identify this please?

Hi,
We have a small piano on our narrowboat. My wife thinks it is a Knight but, I can't find any maker's name to verify this.
The dimensions are:-
L = 42.5"
D = 21.5"
H = 36.5"
The only distinguishing marks I can find on the inside is a serial No. 28932 and HD K35 stamped on the frame.
Any help you can give would be greatly appreciated.
Many thanks
Tom

Open the top lid and look inside on the frame; if it is a Knight (and I think it is; wives are nearly always right...) the name will be on the gold painted iron frame inside.
