There is a clarification needed. TR4A was a chrome handle version of what
then became the TR250 and TR 6 switch. The plastic covering came on the
250's and 6's. A chrome TR4A OD switch is as hard to find as a TR 4 OD
switch. They just can't be found. The 4A's replacements were supplied with
the plastic covering.
