All these tubes are European with 30mm digit height. Although slightly smaller than the more well known IN-18 tubes, these are very beautiful and reliable tubes. Look on ebay for any of the above tube types. The Orange coated tubes are fine too - you can easily remove the coating by soaking the tubes in hot soapy water. The coating just peels off like a decal.
