Any additional information would be appreciated.
This information may be posted or re-printed provided that www.linkertcarbs.com is indicated as the source.
Where a question mark is shown next to an application, it is because that is what I found to be the use over the years, and am nearly certain of the application, but have not found conclusive period printed data.

  *We believe the Indian "bean pot" bowl was actually  introduced in mid-late 1939,
which is why it is legitimately found on so many late 1939 DLX Indian Schebler carbs.
Schebler also made a brass bean pot bowl, the DLX55, with the fixed seat, but very rare and I am unsure of exact application, but it was used on some brass DLX carbs & did precede the aluminum bean pot bowl by several years. We find it rarely, and then only on Schebler carbs that we believe were used racing. .
