Hoo boy - the world of Mabie Todd numbering. It gets messy.
First off - is the chatelaine top solid gold? If so, then its a different number. Lets assume its gold plated.
Kind of tough to tell from the picture, but there's both a slim model and a slightly thicker model. Lets assume the thicker model.
Then the band - they did bands like that, but the catalogs don't show them on the chatelaine top, but typically on the full size pens' cap bands. So, lets go for it that way.
This would be a 332/10
First 3 - Chatelaine gold plated top
Second 3 - slightly wider pen (smaller one would be a 2), screw top
Third 2 - nib size
/10 - that is for an engraved cap band, but not specifically this floral pattern, so am likely wrong on that number, but that what the catalog offers. There should be a two digit number following a "/" that defines that particular engraving, but who knows what it would be?
Now this is a model number a retailer would use to order it - its not like there's a pitchman on TV saying "buy the latest 332/10 Mabie Todd!". Greenie's description is probably closer to what the retailer was telling the customer at the time.
By the way, ringtops are not necessarily women's pens. I just received a Newark Secretary pen in the mail fresh in a box, and attached to the ring at the top is a man's watch chain. Men kept these pens in their vest pockets attached to the watch chains. Admittedly, once its attached to a watch chain, it can't be posted (easily) and therefore requires a pretty small hand.
