270 and Secretaries The two most important securities are 21/2% NATIONAL WAR BONDS (1949-51) and 3% SAVINGS BONDS (1955-65). The main difference between them is the period of investment, an extra 1/2% per annum being payable on the longer-term Bond. Choose whichever suits you best. Both are available in units of £100, or any higher multiple of £50, through any Bank or Stockbroker. Interest accrues from date of purchase and is payable half-yearly. Income Tax is deducted at source. The 'Partnership' firm should not overlook 3% DEFENCE BONDS but should remember that no person can hold or have an interest in more than £1,000 worth.
