I’ve recently installed Summerland Chuffers in both of my engines - very pleased with the results, they sound a lot louder and ad a lot
to the operating experience. Got them thru NGT Models, recommend them for good service and prices.
Interestingly, the 40 psi Plantation engine sounds slightly louder than the 60 psi WD Baldwin - possibly because the Plantation
has a slightly larger diameter stack for the chuffer to resonate off of.
So now both of my engines are accessorized with; Summerland Chuffers, WeeBee pop valves, and Accucraft lube drain cocks.
Next steps whistles, possibly Regner?
