I have a steam engine casting kit I started to build in 1971. One of the castings wasn't machined very well so I ordered a new part from Stuart Models in England. Now the castings included with the kit that many years ago were beautiful clean castings. Today the new part came in the mail and I would be ashamed to send this part out the way it is. There is as much flashing on it as there is casting. Is this typical of the current day Stuart models? I have built quite a few models and have several in the queue to be built and none have castings that look this bad.
