  <dc:title>Letter from Jan C Czechowicz to A V Hill</dc:title>
  <dc:description>With Hill's 'encouragement' has completed a 'special device for bursting the shrapnel bomb 10-30 metres' above ground - has sent it to the Ministry of Aircraft Production, who found it 'flawless' in design but noted that similar things were already being made - does not think that such bombs are being made - asks for Hill's advice.</dc:description>
