Any Hoover experts who can pinpoint Constellation mfg. date?

I've hunted around in archives up here even, and still cannot figure out how to determine a date of MFG. on a Constellation. I picked up a Constellation 454 today, and I'm *fairly* certain it is 1966 model year, however it has a very short serial number (4 digits), and my 1958 model 86 has 3-4 more. This isn't super vital that I know, but would still like to...the s/n as seen in pic is 3751. No other numbers or letters seem to have ever been there on the tag underneath. Is it also possible that this might've been a rebuild at some point and Hoover issued a new tag--seems like Kirby used to do that as well, if I'm not mistaken.

I'm no expert, but you'll probably have to dismantle it. Likely a date code will exist on the motor, the switch, fan blade, some place like that.

If you will watch

The movie Whos minding the store, You will see your Constellation, and it came out in 63

Thanks Hans~ will do. I had wondered if '63 or '64 wasn't most likely....but there were a few folks swearing that '66 was it. That super short serial number makes me wonder if it wasn't among the first of the model out....

How smart you are!!!!!!!!
Equating this cleaner with that movie shows your intelligence.
I got one of those out of a rectory. (don't ask).
