Ok as long as you are in no hurry i ordered something for the car and it was about 3 weeks despite it being in stock and before people jump on the Brexit reason I've just bought a motorbike helmet from Germany and it arrived in 2 days.
They are quite slow. I've had two orders recently which arrrived fine, but took about two weeks. Nothing to do with Brexit - they're just slow.
To go back to your original question, I have had a TES type 1 1641 'red' engine in my bus for about 7 years. No problems so far after thousands of miles around Normandy, Wales, the Midlands, Cambridgeshire, Devon and Dorset.
