1. Don't get too hasty with the lid sealing ring yet, Gary. We're so close now to resurrecting the 105 it would be a shame to bojack it any further.

It would be near impossible to find a correct rubber strip that fits the lip. The suction of the machine pulls the lid down tight and so how the ring has settled over the years will be a perfect fit. If it is not crumbling and you can remove it, a bath in warm water, magic eraser and a saturating with rubber/vinyl auto trim restorer will work wonders.
2. Take the panel out of the lid, inspect and clean the Power Dial disc - this may be the source of a leak on Full Suction setting if the disc is rusty or the spring is weakened.
But wait...there's more!
The only Big Wheel originally equipped with a cotton weave hose was the first Model 77. Lewyt went to their excellent vinyl clad coil hose with the model 88. These rarely split.
I started messing around with and wiggling the hose couplers and the ends came out easily. As I thought I remembered I recalled, the Big Wheel ends are smooth barrels that are rubber cemented to the vinyl hose with collars covering the joint. Both ends swivel on their barrels, btw.
So all we need to do is find a decent soft vinyl hose length that will snugly fit the 1 & 3/16" OD barrels and you're in business. I suspect the hose for the 105 is a creamy white and again I will see what I have in the hose bin over the weekend ('cause I gotta dig for the box).
A Kirby, Westinghouse T-6 or Rainbow hose is the correct diameter which is smaller that a Lux or GE - this I know. And of course it wants to be 7 or even 8 feet long...or more.
More queries:
Does the vacuum still have the rubber exhaust plug in the bottom? If not, I use a bathroom sink rubber plug with the lip edge, carve down the finger ring tab to fit and add a brass crossbar to lock it in place - makes a big difference to scattering dirt across the floor while venting the exhaust out the sides. LOL I bought a dozen of these plugs at Homo Depot because they are a perfect fit, the lip covers the side slots and the center cup is the perfect fit for a Lewyt Scent Tablet.
If the checked Mylar trim panel surrounding the toggle switch is curled and peeling off, no worries. Rubber Boot cement will stick it back down flat. If it's missing, the old rubber adhesive can be cleanly removed with cement solvent.
Ok Mister, I showed you mine. Now show us the 105 in it's before state - for posterity.
