S-W made that chassis for several different customers. Sears, Western Auto, Firestone etc. If you look at it, You'll see that it was built in sections. Also note that the flyback and the yoke plugs in with individual pins for easy replacement. Too bad the H-V cage is missing.

I wonder how hard it would be to find another HV cage. Also, I wonder what the dangers of x-radiation would be if the set is operated without the HV cage?

I'm not familiar with this particular set, but I believe X-ray radiation is generally less a danger with B/W sets than with color, since the HV is not so high. Another purpose of the HV cage is just to keep people's fingers away from what it contains.

If you're not trying to create a museum-quality reproduction, it's not hard to fashion some kind of metal box to replace a missing HV cage. A cheap source of material is old aluminum cake pans from a thrift store. The metal's soft and easy to work with hand tools, which is all I have. You can also buy sheet aluminum or brass from a hobby store.

Another idea is the perforated aluminum sheeting used to make radiator covers, etc., available at home centers. Pretty easy to bend up and pop rivet together and makes for good ventilation as well as sheeting. Make up a template by bending up cardboard first and then using that to cut out the aluminum.

Some sets need the cage to prevent strong RFI. As you say, X-rays shouldn't be much of an issue.
