Copy letter from Robert William Frederick Harrison to The Manager, The Adjustable Shelving &c Co Ltd 'Dear Sir, I am obliged by your letter enclosing plan and estimate for storage shelving. I think the accommodation you sketch would provide amply for our present needs and I will submit it to our Committee in that form. In the meantime however, there are two further questions I should be glad to have answered. (1) Does your estimate which is marked as "delivered free at Burlington House" cover the cost of erecting the shleves? (2) Can you give me a fairly accurate undertaking with regard to the time required for erecting the shelves from the receipt of order?' 28 June 1909
