In the Season three episode “Ricky Loses His Temper” Lucy tries to provoke Ricky by turning on the radio at 4:00 am when he is trying to sleep.

Her bedside clock-radio is a WESTINGHOUSE Model H-420T5 which cost around $30 US in the early 1950’s.  If you can find a vintage one for sale in good working condition you can expect to pay more than that now. Occasionally they turn up on eBay and Etsy and other online sites.
There is one just like it on Etsy but not reported to be in working condition  Click HERE to view
