[GreenKeys] M28 cabinets - skin tight vs skin tight

[John, W9DDD]

Sometimes you need to read something several times.

The TT-176 style cover is described by Teletype as:
Send-Receive Skintight Cover (Rack Mounted)

The LPC206 style cover is described as:
Send-Receive or Receive-Only Skintight Cover
There are 3 part numbers for this cover due to two widths (17 or 17.5") 
and variation in ventilation holes.  The 17" wide can be used with 
extended base for an LESU.
