You're a lucky guy, that is a rare carb. It is either a Schebler DLX 28 or DLX
33 that was an aftermarket carb designed by Maldwyn Jones, of Schebler,
specifically for the Henderson Deluxe. Some consider this carb a significant
upgrade from the stock Zenith T4X, mainly for its high speed adjusting
needle. I run one, and it works very well.

directly from the AMCA virtual library.
