Custom brass focusing knobs. Quite heavy at 9 ounces each so they will help offset the weight of those front heavy Chinese refractors. Diameter 1.5", width face to face 1.06", hole diameter 8.5 mm (standard), hole depth .75". $35.00 plus $5 shipping. USA sale only. No Paypal. Preference given for U.S. Postal Service money order. Personal check ok, but will wait for it to clear.
See photo and thanks for looking!
