Issuer Albrook AFB and Howard AFB. Mintage Unknown. Rarity Very Rare. Manufacturer Tentatively attributed to Meyer and Wenthe Company. Other Catalog Numbers Cunningham's CZ250b. Varieties There may be as many as seven varieties. Per Cunningham, he examined records from Meyer and Wenthe Company, and determined that four varieties were made in different colors (yellow, orange, blue and gold) during the period of time covered by those records. The gold one Cunningham described as different in that it has no dash between "HOWARD" and "ALBROOK". The ones I have examined in person or via image are anodized bronze, anodized gold (with the dash), brown and orange. Function Mess token. Population Count Only the entry by Cunningham is known to me, and I have never seen or heard of any actual specimens in collector hands. I do not know of any recent sales.
