Dear Mr. Griffith: This responds to your October 11, 1974, request for an interpretatio of the application of Standard No. 121, *Air brake systems*, to Canadian-made truck trailers manufactured in Canada following the effective date of the standard and subsequently used in inter-country commerce.; I have enclosed a copy of a letter on this subject to th representative of another Canadian manufacturer, which should answer your question. Please write again if you have further questions.; Yours truly, Richard B. Dyson, Acting Chief Counsel
