A beautiful and well manufactured spinner that would enhance the appearance of any model.
Now the downside, for some reason known only to themselves, it has been decided to ruin the back plate with a 10 mm or 3/8" mounting hole.
Wouldn't it have made more "common" sense to produce it with a 1/4" hole, which is the general size of most engine crankshafts in this spinner's range, thus allowing enlargement at one's own discretion as required !!!!
Sometimes I wonder where production engineers heads are, obviously on the drawing board, not the model maker.
