Enclosed herewith I send a letter from Messrs Wilton & Sons, with a form to sign, also a cheque for the legacy duty which will require your signature. I notice that the mark "A.B" is wanting, but I dare say you will know where it ought to have been pencilled. If the form shd. [should] be signed by the President, please send it on to Glasgow.
