Dennis asked me to take a look. In the time it took for me to search offline and write this message, I see additional posts have been made here. Anyway...
Sometimes, the manufacturer's Billboard ads are all what we seem to have available to us to decide, or confirm years later, what the game is and what it gets called.
1) Look at this Billboard ad for the game identified as "Blue Seal":
Notice that the simple cabinet front looks like your game, a coin slide on the left with a door below it.
Notice that the cabinet side in the ad does not have a small, round Blue Seal on it, unlike our photo example if it:
Notice that the center playfield wheel to the right of the "W" shows "100" in the photographed game:
but the Billboard ad seems to have more than just a three-digit number, yet we cannot read it, dang.
2) Next, look at this Billboard ad for the game identified as "Profit Sharing Pin Game":
Notice it does show the Blue Seal on the cabinet side and its cabinet front near the coin slide is more complicated than your game.
Notice the center wheel to the right of the "W" certainly shows something more to say than just "100" but it's not in focus, dang again.
So, the game called Blue Seal in their ad did not have a blue seal on it, but the other game that was not called Blue Seal did have the blue seal on it, in their ad. Seems we cannot trust the presence or absence of this blue seal to define the name of the game.
The ads seems to indicate each version has more than just "100" on the wheel. Hmm... our photographed version seems to be the odd man out.
We do see the fronts of each cabinet are different from each other, and your cabinet front matches the one called "Blue Seal"
Which game do you have? Unless you have a third variation, it appears. yeah, you have the one called Blue Seal and your wording "Double Score" may be what's in the ad, a better match than our photographed game which is now the "hybrid-looking" one.
Could you make some hi-res images for the IPDB, please? The ones you show here are cool but they happen to chop off the sides of the playfield or just a tad of the cabinet front. Some more direct shots, including both sides and the back side, so we can see if a blue seal is there.
If you have choice of camera, can you use a regular digital camera instead of a camera phone? Maybe that will help the glare. Still, I am grateful for the best you can do.
