I'll put in some pics of a known-for-sure Montague Hollo-glass I bought new in about 1960. I don't recall the original grip cap, if any, or label since I rebuilt it once before it was stolen about 15 years ago. It might have been an easily removed foil label. By luck of FFR, I was given another--identical and as-new--but I don't recall the label or original grip form of that one either, having rebuilt it with better fittings and grip to my liking soon afterwards. The mylar, red thread, and the orangey color of the blank are for sure like the Montague. Still, as mentioned above, it could be a trade rod from a different maker in the style of the time (as seen, for instance, in one of the Phillipsons in this section's header pics). At this time, little variations of fittings can indicate a different maker but may just reflect supplier variations used by the same maker. Similarly, the same fittings may be seen on blanks manufactured by different makers. The Monty reel seat was unfinished aluminum, the rear hood press-fit and peened to the tube. I can't see if yours is identical, but that would only be an indicator, not definitive.
From searching and gathering the pics, I'm remembering a smaller white plastic winding check (that could be a production/supplier change or indicate a different maker) and I ran across a pic of the original label on the refinished rod. You could get more clues by searching Montague and the other possible makers' names here, and examining the pics.
