About ten years ago Steve Coniff and I approached Eric Haartz about reintroducing the original Ford Grain top material. Eric did a lot of research on that, and could not find any of the original rollers for the Ford Grain, however he did come up with the rollers that he is now using for the new TURF GRAIN, which has now been in production for about eight years. It is available from Langs and Macs, but they have both FAILED to discontinue calling the new Turf Grain Colonial! For anyone who doesn't know the difference, perhaps it isn't too confusing, but for those of us who know, it is confusing. I think it's time for Langs and Macs to start calling this material by it's proper name.
I talked to Eric Haartz about 5 years ago, about top material for my 1918 coupelet. He was able to supply the material to me with the same pattern as they supplied to Ford in 1918, I think he is in a position to know. The only difference being the new material is stronger and is harder to stretch.
What difference does it make? I've been trying to get people to quit calling the headlight doors "rims" for years.
