Yes it does look like the one needed for the pans you listed. It may also be for a "933" pan, that tube would be about a 1/2 inch shorter than the one for a 187/699. What it isn't, is the one for use in a 971 pan, a baffle gets in the way. The melling part # for the one you have pictured is 63-s3. the one I have pictured is the melling 63-s4, for use with the "971" pan.
