Howdy Folks,
I’ve recently inherited two Generation (Eb and Bb) whistles, but… they are both full metal bodied? 
Also something interesting to note is there is 3 sets of ‘dual lines’ top and bottom of the Bb whistle?
Beautiful but very old looking beasts… most curious about them, any thoughts?
p.s. both fipples look like a soft alloy… should I presume it’s lead(?) especially with all the old teeth marks impregnated in them?
They went through various stages over time, ‘four generations’ up to the early eighties in the pic above. The ones with the decorative lines are pretty much like the standard late 19th century whistle.
Yep, the blocks on these old whistles (whether Generation or B&S or Dulcet or NoName) are lead. Clean the whistle well and coat the exposed lead with a few coats of clear nail varnish if you want to play. Scotch tape will also work. You just need a barrier between your mouth and the bare lead.
Oh, and don’t chew on the things the way your ancestors did! 
Did any stories come with the whistles? Who played them in your family, or were they just curios?
