Gentlemen:

　　Thank you for your order of September 1 for 20 units of Portable Radio Set A102,10 units of Cassette Tape Recorder B84 and 10 units of Microphone C59.

　　We have in stock Portable Radio Set A102 and Cassette Tape Recorder B84,but regret to say Microphone C59 is out of stock.This article is no longer manufactured because it is rather outdated.A new model C60 is recently developed and enjoys wide popularity.We would like to ask you if you would buy this model instead of C59.

　　The other two items will be shipped to you as soon as possible.

　　Your prompt reply by fax concerning C60 would be appreciated.

　　Yours very truly,
