short answer Mike is no, and I notice that in Steven's recent GMB thread where he discusses un-Registered Jobling designs, he hasn't so far included any pix of this ashtray/cigarette box, though it may be that he has it in mind to do so when things are back to normal.
Jobling is always collectible and seems to have a good following, but outside of Baker & Crowe appears not to have inspired any stand alone books or catalogues, and although reference sources appear in a number of glass books and trade mags., these are brief entries only.
I see there's one copy only of Baker & Crowe, on Abe Books, at the moment - for fifty quid - bit steep perhaps, but like anything suppose it depends how desperate for a copy you might be, and although this booklet runs to only sixty pages, it's a valuable reference source and isn't simply a collection of coloured pix. I doubt that you'll find an equal in terms of detailed information re the factory's/chemist's data on ingredients for some of their famous inventions such as 'Opalique' and 'Jade' (uranium green) - plus there's a full list of the Registered and un-Registered Nos. and related designs, though most of that is now on the Board.
I don't think there's any doubt that yours is 'right' - just for interest, the original Jobling catalogue page for the two versions - 2497 (undecorated) and 2555 (decorated) - reads ……………...…

the green being referred to is uranium green - understandably, we're not allowed to reproduce, here, pix directly from the Baker & Crowe publication.
Perhaps the Mods. might move this one to G.B.
