Swim has sought such E-block through connections, though not vets, at a local animal husbandry and Vet science institution known worldwide. No such block has been found by these connections, who are awfully helpful usually. Talk of this block went around the hive some time ago, and the conclusion was that there was, or might have been, a block called w*********k, usually found in colder climes, and that some old block might still be out there.
Swim cannot imagine that vet catalogs, and equine and bovine supply houses would not list it if it existed, presently. Is this a rural version of the urban myth?
Maybee a better websearcher than swim can find out, his search has been completely negative, for any mention of such, except sometimes in legend, and here.
Beeginning strongly to suspect the biker groups who held the trade for so long May have told some tall tales. Otherwise why several such legends of acquisition and synthesis, spread so widely in time and space, and so coherent otherwise?
