This is probably going to be the same as a previous thread regarding small organs but one thing that I have been curious about is the popularity of house organs.
One particular instrument I am curious about is a four stop practice organ by Skrabl as I wonder how many of these organs Scrabl have managed to sell.
Below is a link to an article on the Skrabl website regarding this organ.
