Greetings,(posted 8373 days ago)As Pete stated, Rodinal is a unique developer and you might have better luck acquiring it through European sources. Calumet has offices in the UK and perhaps they can ship it (calumetphoto.com.) If you're looking for an alternative to Rodinal in a Kodak formulation, try HC-100. It is in no way like Rodinal, but the results on film "could" be similar. There will be no similarity in dilutions. The Darkroom Cookbook, by Anchell & Troop list a formula for a Rodinal "type" developer, but the actual formulation is proprietary.
Regards,
