Ken,
The 282 and 285 filters are 6 pole filters and not 8 pole as shown
below. Here is the TenTec Wiki information on filters.

Subject: Re: [TenTec] Filter information
Hi All,
I have been trying to keep an accurate reference of Ten-Tec filters,
mostly focusing on pre-Orion radios. I have deleted some information
that has been identified to me as incorrect, and added the notes about
the probable application of the stock number 48057 and 48127 filters. It
seems that "stock" non-optional filters generally have a stock number
but do not have a model number. Model 220 may be an exception. Any
additions, confirmations or corrections are appreciated.

Following the number of poles are other numbers that have been reported
seen on these filters. They may be date codes or PCB design numbers.
