| March/April 1954


'On behalf of the National Museum I am pleased to formally acknowledge the receipt of a model oscillating steam engine, designed by William Graham, Carlisle, Pa., about 1880, which was brought in person to our division of engineering'.

'This specimen is an interesting addition to the National collection where it has been recorded as a gift in your name.'

Very truly yours,

Dec. 12, 1934
