Not for sure about that jig, but it looks a lot like my leigh and porter cable which both use a 7/16 guide bushing.
Fire65 - thank you so much for taking the trouble to reply. May I ask you some more detail please? are the fingers and spaces the same size on your jigs? They seem to be the same on mine, but on youtube I see similar jigs with different sizes. Does the 7/16" bushing fit exactly in the spaces, or is it a loose fit, ie you rout in one side and then out the other? It looks like the 7/16" corresponds with the measurements I took, which is giving me great hope! I have a set of Bosch guides, therefore probably metric, but I know a machinist who will easily make a collar if I need one. I have a little Elu router as well, its bushings attach with two screws, so I might get lucky, and a Milescraft inlay kit which has a few different plastic guide bushes.Not for sure about that jig, but it looks a lot like my leigh and porter cable which both use a 7/16 guide bushing.
Thanks again. I've re-assembled the jig and I'm checking what bushes I have. The spacings on mine are 3/8" or just over 10 mm, so even though there is in fact a 7/16" bush in the Bosch kit, it aint going to work. Only the smallest bush in the kit is fitting in between the jig's fingers, and the dovetail cutter barely clears it. Bosch bushings are a unique bayonet fit, not the standard screw-in type, they won't fit the Elu. It's too cold out in my shed to do any more this evening (-6C) so I'll get back to it tomorrow - next step is to mill some wood and commence experiments.The Porter Cable, which looks exactly like the Elu, has 1/2" gaps in the fingers, the Leigh is adjustable. I am not familiar with the Elu router, if the Bosch guides fit the router base I see no reason why they would not work.

Also found a similar Elu jig 400-47 on UK-eBay.
Hey Biagio - thank you so much for your very kind offer. I think I actually have it - is it a booklet entitled:John, just found an old photocopy of the original manual for the jig (English and German). I can scan and post, if you need it. Not great quality unfortunately.
