【答案解析】To whom it may concern, I am in great need of a condenser for my Radio Cassette Recorder of the brand "Red Lantern" produced by your factory. The original one has rusted so badly that I can't get a clue to what the serial number might be. I need it urgently for my English study. If you have the right condenser in stock, please let me know the price, and I'll send you money to order one. If you don't have it right now but know where I can get one, please forward that information to me. Thank you for your help. I look forward to hearing from you! 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Yours truly, 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Li Ming
