Copy letter from A H White for Robert William Frederick Harrison, to Dr C Bolton, 16 Devonshire Street, Portland Place, W. The Society's printers have forwarded Bolton's enquiry about his blocks. They are with the printers but the Society does not permit them being loaned. The Society's practice is to authorize the printers to ask the printers to take electros from the blocks and charge these to the person wishing to use them. Asks Bolton to apply to the Society for authority to have electros made. 7 September 1906
