Tasco 7T-E Serial Numbers

I've got one with a serial number of 760051 and have a friend with one numbered 960632.

Does it have styrofoam inserts? Yes-1970, no- 1960?
No styrofoam involved with my scopes of 76 or 76.2 X 1200 aperture with serial numbers starting with 0, 5, or 7. (two Tascos and a Mayflower). My Sears 6336 scope(76 X 1200) starting with serial number 2 does have styrofoam in the OTA case. #2 in the serial number would indicate 1962, (or 1972?), however these mounts are said to have only been available through Sears in 1965/1966 (or so). I don't have any Tasco 7te scopes, but my two Tasco 7te-5's serial numbers start with 7 and 9. One came with a case which has styrofoam, and one came missing the case, one tripod leg, the eyepieces, the sun projection hardware, probably some other stuff that I've forgotten about...and it was the best $12 I ever spent.
Anyway, here is what I know and don't know...
I have/had 3 scopes on tripods of 76 X 1200 (or so) which have the second and third number in the serial number in common -70---
I have 2 tasco 7te-5 scopes with the second and third number being -61---
I have a pier mount Sears 6336 76 X 1200 with the second and third numbers being -72---
John S. has two of these same scopes which are also -72---
The 7te models apparently used #-60--- to define this vintage.
So serial # -60--- = 7te, #-61--- = 7te-5, #-70--- = 76.2 or 76 X 1200 tripod mount, and #-72--- = Sears 76 X 1200 pier mount scopes.
On Darrel's list there is at least one with the # -71--- why just one?
I do like the first number being the production year, but still have a problem defining decades with this system. Of course this becomes interesting to us many years later, but what exactly was the purpose of attaching an individualized serial number to each small (almost toy) refractor of the day? Accountability, pride, hubris?
My Royal Astro branded scopes all have serial numbers no matter who the final importer/seller was... Tasco, Sears, or Mayflower.
Of some other vintage scopes I have... Nippon Kogaku, Asahi Pentax, and Swift all have a serial number attached. A year 2000 Tak also has a serial number, as does my 1980's C-8.
The scopes that don't have serial numbers are my 1950's Goto Kogaku(s), a Criterion RV-6, Mizar and Atco (both HOC), and a 1954 Unitron 114. Why not?
What are the long and short term benefits of including a serial number besides quality control? Especially numbers whose meaning are open to debate 40 or 50 years after production? And why use one digit of a current decade? If you were springing for a 1957 vintage Bordeau wine but it was just marked "7" how sure could you be it wasn't a vintage of say 1987 or 2007 instead?

But the styrofoam vs. wood is a sure indication of which is the most recent manufacture - at least you would expect that, but there may be exceptions.
Meanwhile, if you find any of that 1957 Bordeau, better let me taste it just to make sure it's for real.
