The Kroger's house contained spying equipment, including code pads for coding messages, a long-range radio transmitter-receiver for communicating with Moscow and photographic material, as well as large sums of money. It took several days to unearth all the equipment. Other items, including fake passports, were not found until after the police had left. The MI5 intelligence officer Peter Wright stated that the Krogers' radio transmitter was not located until after nine days of searching. Over the years, during subsequent renovations, several other radio transmitters were unearthed. Large amounts of money were also found in the homes of Houghton, Gee, and Lonsdale.
