Thanks both youve been invaluable with your advice/suggestions this far. It has been hugely appreciated

This appears close / similar to what you have. I haven't done a detailed comparison but I will leave it here (3 pages):

After a quick look ..... doesn't say what the maximum sprocket size though

Your front derailleur appears to be in the same catalogue too

I do love the old hand drawn catalogues. Such a skill in itself.

Can't find anything written about the capacity, split the freewheel into quarters and try and count the teeth

Alternatively you can translate this distance to find the maximum size

Thanks mate, nor can I or @Woz find any capacity reference. Good idea re quartering the freewheel.

Probably best idea here. So long as the large sprocket has clearance with top jockey wheel/cage all good

@WhtANightmare if you measure the distance between the wheel spindle centre and the top of the mech cage, I will measure some freewheels.

The top edge of the inner cage plate has to clear the largest sprocket, looks like the jockey wheel is set lower
