Bestwell Magna-Sight optical focuser for darkroom enlarging. Much nicer to use than the typical grain focusers that require you to be all scrunched up under the enlarging lens. This one lets you stand far back and see the image clearly from a distance. Good condition, works perfectly, has some minor surface blemishes on the mirror which have no effect on anything. US sale please. $15, plus $6 shipping by insured priority mail.
