Even if (like me) you don't have ready access to a set-up lathe, it is still possible to turn the older Romford flange down to a more acceptable profile, like the Markits wheel in the centre, using no more than an electric drill, a suitable needle file and a piece of fine wet & dry paper. I was doing precisely that last week, before my plans became stymied by my inability to remove some glued-in crankpins from the wheels concerned.
The above procedure only took minutes for each wheel, although undertaking such an operation with a mains electric drill on your own lap is done at one's own risk, of course, with appropriate PPE being a good idea too.
If you do have access to a lathe, however, then dealing with the older Romford flanges ought to be even easier.
