Since the 413s and 414s were aftermarket replacement carbs, there is little demand for parts; thus no economically feasible excuse to mass-reproduce the accelerator pumps.
Hand-made parts are EXPENSIVE!
And the carburetor certainly appears to be a 413s.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | |
