Here is the Pyrex I would like to know if it is different enough to be some other cd number than a CD 128 shown next to a regular CD 128 Pyrex it is narrower at the dome and tapers from the base up and is shorter than the regular example the glass is thicker walled and the base is distinctly rounded on the outside edge with a base mold line substantialy higher than the normal Pyrex, the wire groove is also narrower than the regular type by 1/8".

This has been determined to be a Pyrex CD 128. However it may be considered as a Round Base example that is previously unreported until now. It has been shown in person to John McDougald and he has made note of the new discovery.
