Okay, this one is tough. I don't feel good about any of my tracking on this, but I'll take a couple of swings anyway.
ASA E6-B Flight Computer
E-6B was developed by Lt. Philip Dalton.
Philip Dalton was born April 1, 1903 and died on July 25, 1941.
My 3 best guesses on this:
1-April 1 (his birthdate) sticks out. So it could be a reference to April Fools Day. Possibly the movie, or just possibly an original house based on April Fools Day folklore and traditions.
2-1941 is the clue. Couldn't find anything specifically on July 25 of 1941, but the movie The Wolfman (among others) was released in 1941 - so with this guess it would be some sort of Universal Monsters versus house.
3-July 25 is the clue. Nothing specific on July 25 of 1941, but July 25 happens to be the birthdate of Irwin Yablans, who was the executive producer for the first three Halloween films. So this guess would be some sort of Halloween house.
Again, I don't like any of these guesses. I'm not connecting at all on this one unfortunately.
