This balloon was built in 1984 by the Dutch Limburg-based factory Price Balloons, founded by T. Price and A. Kurvers. It was destined for Pelgrim, a manufacturer of heaters and kitchen appliances. In 1984 registration PH-BAM was reserved for it as "Price AX7-77S" c/n 002, but it was never officially registered as such. Then in 1986 registration G-BMZT was reserved for this balloon, but it is not listed on the G-INFO website because here too the registration was never taken up. Despite not being legally registered anywhere, the balloon made several flights in the mid and late 1980s. It is seen here still wearing both registrations, albeit marked as just "BAM" instead of "PH-BAM".

This aircraft has quite a history: it was first registered as G-OPPS in Mar-1990, in May-1990 it became F-WZCI, in Sep-1990 it was registered F-GGYN, in Apr-1991 it reverted to G-OPPS, in Apr-1999 it was registered G-PELG to Jan Groot (name mentioned under the cockpit in this photo), in Dec-2002 it became HB-MSV, in Jun-2010 D-ELRM and in Nov-2016 OM-ONS. The sponsor Pelgrim is a manufacturer of large kitchen appliances. The aircraft is seen here landing after its show.
