  Thanks.  The clue about pushing the gasket into the endcap hole
a bit and then inserting the tube into the gasket causing it to seal
is mint.  The brass retainer then keeps everything in place.  I like it. 
Makes sense.

  Anyone else with two cents to add.  Apropos gasket materials, vintage
or modern?  Any photos of it being done would be appreciated.

Thanks,
Wayne
