The apparent disconnect in some of this back and forth stems from a core feature of this pen, which Daniel-- as expected-- caught early on, but which still carries significant collecting import, imo.
The pen has features which are anomalous for typical, mainstream (i've come to like "main sequence" from my astronomy days) Sheaffers, but which are less anomalous once the pen is put in context.
Mike is quite right. Roseglow was introduced after Sheaffers-- as illustrated in numerous USA-catalogues-- moved to the smooth "radius" clip. As with all the "late" colors, the two top tiers (white dot with Lifetime nib, and non-white dot full girth with #5 Feather Touch) nib have the radius clip. Even with USA pens, the two lower lines (3rd tier with non-white dot cap and #3 nib, and Junior 4th tier with "Junior" nib) have the slightly older style "flat-ball" clip that is marked still "Sheaffers". Exceptions exist for off-catalogue cap-bands (double , triple, jeweler's, etc). All non-gray striped-era pens have gold-filled trim, save that all Junior, 4th-tier pens have chrome trim.
This pen is an anomaly in that context in that it is a full girth pen (thus at least 2nd tier), but has:
- chrome trim
- full-ball clip (discontinued by Sheaffer years earlier)
- not showing in pic, a #5-30 (also earlier-seeming than the expected #5 Feather Touch), but with a more odd finding, a two tone effect not seen or catalogued in USA for the earlier 5-30.
Daniel nailed quickly that the pen is Canadian. Thus the "rules" as outlined for the Sheaffer main sequence (based on observation of pens and from catalogue data from the USA) need not apply.
The pen *might* not be anomalous for a Canadian Sheaffer. It is anomalous relative to expectations for USA-made pens. The charm then is that certain apparent anomalies can clue us in to the pen's Canadian origins. I like that.
Canadian Sheaffers from 1930's-1940's fall well under the radar for most collectors. They can be found with some serious deviations from general expectations and offer some cool variants. Pens with WASP type clips are found. Various reversal of trim. Even non-Balances done in striped Balance plastic.
The pen in this post I believe still warrants the "reverse trim" label. Whether or not it is a catalogued Canadian variant (I've seen no Canadian documentation for any Balance), it is still a minority finding, based on my experience, even among Canadian pens.
I have seen a fair number of "reverse trim" pens of Canadian origin. They are well more prevalent than USA pens of this sort (I'm scratching head to recall i've I've seen any reverse-trim USA made pens with normal cap-band), but that they do crop up does not mean they were... routine.
Per Daniel: This is the expected configuration for the Canadian model at this position in the line. If it is US production it is quite anomalous.
Those are strong words. If this is the expected configuration, then one would not... expect... to see regular yellow trim. I believe I have seen that. Too, I've not seen catalogue, so am not sure Sheaffer promoted this chrome-on-Rose as the typical pattern. Some support data is invited... 
As Daniel suggests, were this a USA made pen, it would have greater cachet. Still, it definitely is a "bonus points" pen. As aside, I note that I am not certain I've ever seen a radius clip (used routinely on the top two Balance tiers from some point in 1935 though 1941 for USA made pens) on any Canadian Balance. regards David
