Garrett wagon info and brochures wanted

[BIG Trev]

I'm looking for an original copy ot the spare parts book for Garrett Undertype Piston valve wagons, can anyone out there help me with this? It's to go with my undertype wagon 34315.

I'm also interested in purchasing any Garrett paperwork including brochures, catalogues, advertising books, cheques, letterheads and envelopes or bills, I'm focusing on wagons both over and undertype but any other Garrett product will be considered. I'd also like to get hold of original RIchard Garrett spanners if any exist outside of the Longshop Museum?

One last request. I'm still chasing any information on any Garrett wagons both under and overtype and trailers that were shipped to Australia and New Zealand. Thanks for any assistance you can offer.
Cheers BIG Trev
