Seth Thomas (missing the key to set alarm)

by Emily
(Lynden, Washington)

For our wedding in 1975, we received a Seth Thomas No. 837 Tuckable, brass case, blue dial alarm clock. It is missing the key to change the time for the alarm. Are these keys available and if so, are they expensive? I'm hoping to get hold of one and screw it back into the clock and have no further problems :). Maybe wishful thinking.

Thank you for your help.

Sincerely, Emily
