Geo's reference to Salazar's articles is a good idea. Regarding those fantastic WCC cases, I've got about 1,400 WCC58's, about 1000 once fired and the rest fired about 12 times; good for at least 20 more. Also have about 400 new, unfired WCC60's. I'd sell them and pay shipping if I had a good offer. Both types have probably been used to set more records and win matches than any other two makes and types.
