Tool study #1: Hobbies block planes

Ever heard of Hobbies planes? I found them by accident on eBay, and have put together a study on the ones that are now in my collection. Hobbies is a British model maker supplier, in business since 1895. At some point they made their own tools, including planes, fret saws, and drills. If anyone has any information on the missing two planes (i.e specs, pictures), or on Hobbies planes in general, I would be happy to add it to the study.
