Very nice. Thanks for making the effort to post them.
Re-reading your original question, I realize you asked specifically who made the Lucky Twelve.
The manufacturer was Oliver Whales of Fun City, Redcar. It appeared in 1958 and was evidently a ripost to the Bryan's Elevenses of 1955 which, by offering an amazing eleven winning cups, had become something of a roaring success in allwin terms. The Elevenses achieved this by employing long springy pins set into a metal block behind the playfield. I think the Lucky Twelve has standard allwin pins above the gallery so it's probably a bit on the generous side. Anyway, it's rarer than the Elevenses but coming from the prolific Whales stable, not as rare (or desirable) as the Parker's allwins.
