6.50 mm reamer, your old guide and the new tappet
-JdK- Viktor is reproducing OHV tappets; they are made slightly oversized (drawing below) so you can use your old guide which needs no more than a cleanup with a reamer. The quality is excellent, I've fitted a set to my 1927 Model 18 years ago and they seem to last very well. Do check the dimensions with your old set of tappets, there seems to be variation as usual. Contact me for Viktor's details.
