I've been tiding up a manual I have - it's a pretty poor photo copy.
Maker long since gone.
At the bottom of the front page (next to the list of directors, etc) is a logo of what looks to be a heraldic lion holding on to a flag pole with a banner at the top. Totally unreadable. Dates from the early 1980s. Looks similar to the lion that was stamped on eggs. Anyone remember what it signified? It's not the company logo. Possibly some trade or export award?
