Membership card, removed from the card index of the Mountaineering Association. BR had been President of it for 20 years as of April 1966 (document .111354). The Founding Chief Administrative Officer and Director of Training, J.E.B. Wright, told him so in his letter of retirement after 21 years of service.

The card has 3 addresses for BR, the first 2 of which are crossed out: 18, Dorset House, Gloucester Place, N.W.1; 41, Queens Road, Richmond, Surrey; and Penrhyndeudraeth, Merionethshire.

18 Dorset House was BR's second address at Dorset House. There is no record of his using the second address before 1948/10/11. 27 Dorset House was used as early as 1946/12/08. Thus BR's presidency may not have begun as early as 1946.
