Thanks George, I've seen the small case, but this one appears to hold just under 100 pipes (97 by my count). The advert does say "case similar to shown", so I assume these may have been custom and/or made by various companies for them.
Sadly, its in on an outdoor porch which explains the condition. I asked my daughter if they could determine which shop it came from (seems unlikely). A case of that size must have come from a pretty large shop with a big inventory?
