Hi Tony , Good to see You here too. I usually desribe the Aging on Antique Ivory & Brown Micarta(It Ages Brown- doesn't start out that way & never Did . Sometimes both of these can start out yellow or Natural inside)There are some Papers & Tan Linens that are Pressed for those Colors, but the old Vintage Aged Brown Ain't one of em' . I Assure You ANY Micarta I sell is Expensive, Bleached linen/cotton, and Micarta Brand Usually W-house or I-P and IS what I Say it is . I've seen the people at e_ _ y that dont Know, Have or know Anything about Micarta . There is Nothing INFERIOR about My Stock unless somebody is Expecting Antique Gold or Ivoritr from these 2 batches. I dont sell the Brand that starts with an 'N' & never have. Wish people would Ask questions before they buy like Leatherman did, Rather than come at me with half baked Information. I cut Blanks (with NO complaints - but praise) for the Kind of Randall Customers That have the Maximum of builds put in from the from All the Dealers All Year/Every Year. I hate to mention this here but I'm told I know more about MICARTA recipes than Any Dealer (and stay alive from being TRUSTWORTHY), sorry. I can tell You about the Insulator Handle stuff (Molded Linen) Any Paper or Linen Recipe or Color Recipe We use on Handles (Randalls & Customs ) of ANY Vintage Westinghouse or Intl. Paper Recipe whether Decorative or Not. I Highly Doubt I can learn Anything about Westinghouse Micarta here , I've learned most of it from Professional Micarta dealers who know hardly ANYTHING about our world. I came here to Educate mainly. Asbestos is a whole nother world of misunderstanding as is sometimes shown in the Cue & Knife world. Epoxies were used By WH & IP in resins such as My Ivory/white linens that preserves just as Nicely. Kenstix
