Lusty caravans

Has anyone heard of this brand? I have just bought a 1951 teardrop caravan, on the registration sticker it is called a 'Lusty' - great name! It has a square end, unlike most teardrops, because the back panel comes out and makes a table. I tried to post a picture but the attachment button was greyed out. I can't find anything anywhere about it, and I would love to know more.
Cheers
