BAS,

What about COW GUM? Manufactured in the UK by Cow Proofings Ltd, Slough
Berks.

Also Richard Sullivan in his note on the Gum Substrate Method (30/3/96)
mentions the use of dry mounting tissue.

I would like to investigate Richard Sullivan's method myself, but can
anyone inform me where I can obtain Bregman register pins and Berkey
tabs? Preferably in the the UK. If not available in the UK, is there any
supplier in the area of Chicago USA?

I can at a pinch make my own 'berkey' tabs, but I would prefer not
attempt the Bregman Pins!

Alex.
