Harry at Second Shot just serviced my OM-2 and just wanted to recommend him: www.secondshotrepairs.com
Old foam around the prism was everywhere, mucking up my focussing screen. He's cleaned it all up, found a replacement screen, and gave me new batteries.
Really pleased with the result
Yes please. A really worthwhile job you do on this so thanks . I haven't had need to use any yet but a list kept up to date is invaluable. In recent times we seem to have lost some of the best repair shops in the U.K.
