- 440 Timer Face Plate to replace older metal face plate when switching to Empty 440 Timer Case.
And the "Case" has been long obsolete.
We would recommend new Timer Assembly ( 460TC ).
NOTE: Some 440 timers had the numbers 17C95-1 on the front cover.
These are usually old Autotrol 155
Valves ( and you might find 1550-TC on the top label ).
