It reminded me a recent article of the blog written by one of my friends, who is also a Tolkien fan in Japan. She noticed one main character in a Japanese TV drama was playing a piano with the unique logo "...ENRY TOLKI...", and supposed from the information on the internet that it might be a piano by Henry Tolkien.
She and I am not sure it is true or not because we have not asked the TV station about it, but I believe Henry Tolkien's piano was also imported to Japan.
Taken together, Henry Tolkien's pianos were exported from London not only to Brazil, but also maybe to Japan, the quite opposite side of the earth!!
No they are not, it looks like John Benjamin Tolkien (J.R.R. Tolkien's grandfather) was Henry's older brother, though nice to see this confirmed if anyone can.
