Thanks dan.Yes. The XP8 drums had two layouts that had deep toms and an 18x22 bass. 'The Londoner 5 XL', and 'THE BEAT'. First shown in 1982-3. I have never seen one of these sets. Must be pretty scarce, that's for sure.
I did have a 'Heritage' outfit from that era with a 16x18 bass, 10x10, 12x12 and 14x14 toms.
