Clarence Trimpe sons run the business in Seymour IN. They are great people and they run a very knowledgeable business. I run Trimpe bars and they wear great. They also run all colors for corn head snapping rollers,cones,etc.too.
I have a set of Trimpe rasp bars in a M2. I bought them at a salvage yard. I've been running them for about 6 years and they still look as good as the day I put them in. I put about 250 acres of corn and 250 acres of soybeans through the M2 each year. I highly recommend them. T3
