Guage Reader Lenses for Older Sherwood Magnum

[ontdiver]

I have an older Sherwood Magnum mask with guage reader lenses with +2.50 magnification that are no longer effective for reading my large face spg. I would like to keep the mask as the fit is perfect. Does anyone know of a possible source for Sherwood lenses with higher magnification? TIA

Try adding a lower power stick on type magnifying lens to the existing.
