[TRADED/FOUND] 1.25" eyepiece barrel (with retaining ring)

[Handy Andy]

I am looking for a 1.25" barrel (with integral retaining ring) to suit a Meade RG 7mm Orthoscopic eyepiece. I believe the eyepiece originally had the aluminium type barrel/retaining ring - there were also chrome barrelled versions sold by other companies (eg, University Optics). Any helpful leads most appreciated...
