I am looking for info on Rectangle mold chips. Any and all info is appreciated.

1) What were the starting and ending dates for the manufacture of this mold?

2) Is it accurate that the manufacturer was Langworthy.

3) I believe Langworthy is still in business. Does anyone have an address, phone number or e-mail address?

4) Is there any other source for info or records on this mold?

Thanks...
