Sorry, I just realized my husband had not done the second book of manuals - and it's the one with all the National and New Home ones.
So I do have manuals for all four of the National types shown. (Including the Expert BT). I'll see if I can sweet talk DH into getting that one up on the VSS board.
BTW - the second picture in Janey's post #4 is mine - that is the Expert BT. I have that one in a hand crank verson too
