Talk about a hard luck story!  In 1941, Montomery Ward had the great good sense to have Telechron make them an alarm clock with a simple, attractive case and it makes the top of Counsumer Reports Best Buys List and what happens?  Pearl Harbor!  45-1000 was the brown bakelite model, 45-1001 (above, right) had the ivory case and brass ornaments and the 45-1002 had both plus luminous hands and dial.  From what I can see "45" was Montgomery Ward's catalog code for clocks whether or not they were Ward-branded clocks but the last number is the identifier as you already guessed.  In a pinch, the case is a replacement home for the Deputy or so says the Parts Catalog.
