It sounds very much like FX-37 with bromide instead of iodide.
Helen,
FX-37 is a variation on the Ilford Microphen formulation (Phenidone/Hydroquinone/Borax). Note that Crawley's published formulation contains a pretty hefty dose of sulfite, plus KBr and Benzotriazole.
The FA literature implies that their developer is a low or no sulfite developer.
The easiest way to achieve long shelf life with a P/Q developer that has no or low sulfite is to mix it without water, using either one of the glycols or triethanolamine as the solvent.
The dilution ranges that FA cites imply that their developer is more highly concentrated than FX-37. This is another argument for use of triethanolamine as the solvent/organic base.
