[Boatanchors] SB-300 & SB-400 parts & manuals needed

[Perry Nettles]

All,
I am in need of Manuals for both the SB-300 & 400. I have a partial one for 
the 300, but it seems I can only find one for a SB-401 and not the earlier 400.

Also need a Nylon spiral follower for the dial mechanism. The heathkit part 
number I can come up with is 266-74. This is from a SB-102 manual, and 
seems to be the same part. If this is incorrect, someone please straighten 
me out. Hey..Hey!

73,

Perry, KF5SMU
