Jet block (1 in. choke)
Jet block for the 1 in. choke Amal carburetter used on the 1964 TR6, carrying the main jet in the float bowl.
This is a jet block for the Amal carburetter, listed in the parts book for the 1 in. choke size. The jet block is the casting inside the float bowl area that carries the main jet, and it's a part that wears or gets damaged over time from fuel varnish, cross-threading, or a dropped jet during a rebuild.

The catalog entry ties this one to the TR6 figure for 1964, so it's from the Amal carb used on that machine in that model year. If you're rebuilding an early TR6 carb and the jet block is corroded, stripped, or missing, this is the number to check against what's currently in your bowl.
Given how specific jet blocks are to bore size and carb variant, it's worth confirming the choke size and carb type stamped on your unit before ordering, since Amal carb internals from this era aren't all interchangeable.
