This fantastic book is full of 'finished goods' available for sale to the trade in 2001. I have just scanned the vacuum pages in, but they are complete with prices!

This lovely book dates from I imagine the early 1990's and shows the range of Airflo pattern bags available at the time!

Not sure I fully agree with this document, as these bags kill Miele machines, however for older vacuums with less airflow they are OK, but this is a proud advertisement to the trade of the new 'Hepaflo' type microfleece pattern bags!

This little printed document shows all of (or most of) the Qualtex motors for commercial vacuum cleaners, a handy reference diagram for finding motors for obscure vacuums!

This very recent brochure from the trade supplier Maddocks shows their range of Numatic products (although probably only the best sellers) and their prices as of early 2018.

An undated internal magazine from Maddocks Europart here, including their top 25 selling items, which must date it to the early 1990s going by the Dolphins, Twin Turbo's and Aquamasters in the list!
