There is a company that makes reproduction glass dials. Unfortunately We in the radio restoration hobby, are having some problems getting things done with this company The company is ”Radio Daze’ and they are in the United States.
Several members of the Antique Radio Forum and others have tried contacting the company lately with no success. [covid 19] I think
They do very good work and I have used them on several occasions.
They do have a reproduction glass for a CGE model KL-56, but I don’t see one for your radio.
In the past I have sent them broken dial glass and they have made me a new one ,, but by the looks of your glass, there is too much missing.
Your best bet might be to put a WTB add on various forums and see if someone has one they are parting out
Here is a link to their site.
