Yeah, I see that now - although my recollection of the tommy cooker tablets was that they were square and didn't smell fishy at all - they did have a bit of a waxy feel to them.

Thing Is the one I used was British/Canadian milsurp - I haven't seen a source for the
tablets anywhere. Knowing that it is the old tommy cooker stuff though you could probably find them somewhere here - I just haven't seen them in my usual haunts.

If I see them somewhere I'll let y'all know.
