[Hallicrafters] SX-28 vs. SX-28A bottom covers.

[Waldo Magnuson]

I have a SX-28 with a bottom cover.
I recently acquired a SX-28A w/o a bottom cover.
The 28 cover is the correct size and with the screw locations in the 
right place but some of the tuning holes appear to be slightly off.  
Does anyone have a 28A cover that a tracing could be made from?  I 
would appreciate receiving a 1:1 tracing.  Thanks.
