It does look like a blue and gray version of my Mayflower 814. It's marked diamond BOL, which I think is "Bushnell Optical Labs", which they used for special projects with Japanese manufacturers. So it could definitely be an SYW (or APL?). Here's my box minus the OTA. SGW has rotated two of the styrofoam pieces wrong (and left the objective cell off to rattle around).
The one currently on SGW is most likely a APL and most Sky Chief Jrs that show up are APLs. Some are marked as such and some are not, but they can be identified as being APL by some of the characteristics of their components. For example the angled finder mount on the tube is seen on some APLs but never on a SWY nor the slightly rounded inner surface of the outer tripod legs. The same thing applies to finders mounted on the focuser. Some APLs have a straight mount on the focuser, but no SYW made 60/700mms has ever had the finder mounted on the focuser. Their mounts are straight and mounted on the tube. It's kind of complicated but once you know it's easy to tell.
Some SC Jrs may have been HOC but I don't remember ever seeing one marked as such and since some APLs can have the same. features it would be hard to tell. Just like Mayflower the newest Jrs were made by SYW and can also be ID by their details and usually have SYW on the pinion cover. It appears that Bushnell and Mayflower used all three of these makers. Manons can be found marked HOC and APL, but a SYW Manon has never been seen. One day maybe I'll do a thread with photos illustrating their differences.
Personally I think there's some kind of direct connection between HOC and APL with the HOCs being older.
As for the drawtube, these have a one piece rack tube that retracks all the way in when stored and yes a Vixen 1.25" VB will fit.
BTW, your foam inserts should be rotated 180° with the legs in the back and spaced like below
My incomplete spare 814 is in the box.
