This question may be better aimed at a steering wheel enthusiasts forum, if there is such a thing, but thought I’d run it past you erudite folk first.
I recently bought this moto-lita online and am delighted with the look, but only on receiving it did I realise that the centre hole is smaller than the current ones. The boss it came with (not motolita branded and with no number markings) sort of fits on the column of my early spit (and the horn works!) but it rubs and graunches a bit on the flange.
Looking at ML ‘s site tells me they can supply a B20 S/C. (small centre) boss that should fit better so i have it ordered, but I’m struggling to find any other info on these small centred wheels, other than that they are early and quite rare.
Does anyone know the story behind them, what if anything they were originally fitted to and and when, and why they were discontinued? To my eye it looks rather better than the current larger style.

John,
I have no direct knowledge, but would remind you that the Triumph steering column was used by a wide range of low production makers over quite a few years. So something originally specified for (as an example) a Gilbern might now be available as an aftermarket wheel.
All the best,
Paul

Paul and John
I have one of the small opening Moto Lita wheels with wooden surround. It came in a kit for the clamp on hub for the TR2-3. They had a bolt that slide into the shaft, kind of like the universal on the steering column on the Spitfire and other Triumph cars.
I'm in the process of having a small hub center turned down to fit the smaller ring and have already drilled out the holes. Still has 9 holes
My buddy with a Cobra recalls seeing them on the repo's.
I got it for the Roadster, but decided not to lose the original controls. It is a odd ball, but will look great on the TR6. Oh, has about 1 1/2 inch dish.

The steering column is adjustable, so if it rubs it just needs adjusting.
Moto-lita made wheels to serve the aftermarket as well as some OE manufacturers.

I am a bit confused by your OP if you are talking about a small centered wheel or the wheel to column adaptor.

As Paul says, the Triumph column was used on many cars Lotus, TVR, Bond etc. Many added their own selected wheel from an aftermarket supplier (such as Les Leston, moto-lita, MilleMiglia, Formuling)

That does look rather nice.

Sorry guys if I didn’t make myself clear.

The centre hole encircled by the bolts on a current moto-lita wheel has a diameter of 82.8mm while my wheel’s hole measures just 57.2mm, thus requires a different sized boss/adaptor/hub, whatever you like to call it, attached by the nine bolts, between it and the steering column itself.

I attach a picture I’ve just found of another small centre wheel alongside a standard wheel for comparison.

Moto-lita sell a vast range of bosses/ hubs to interface their standard 82.8 hole wheels with car makers’ different columns, diameters, spline counts etc, but only one boss that fits the small 57.2 hole wheel, the H20S/C, which luckily for me, fits the Spitfire column splines. Also various Reliant, TVR and Lotus cars

So my query was really on the small wheel internal hole size and it’s history, and only incidentally on the boss, though I am curious as to why M-L only make a single boss for it.

John, the first wheel is the one I have, small center hole for the TR6 now.. I'll try and get a picture of the hub in a few days as it's at a friends shop to be turned down.
The hub was designed for the large hole but it had the small OD hole edge for the small wheel. I'm thinking it's so the original horn button could fit into the center.
I did search for the correct hub for the '78 Spitfire, but could only come up with the later large hole one as the splines are different. So I took the wheel off the TR6 and will fit it on the large one for the later Spitfire and will use the reworked hub I had for a TR6 on this one. It's never easy.

Hi Wayne
This is the new B20 SC boss that arrived this morning from Moto-Lita, if it helps. As luck would have it I’m away from the car for the next week so can’t fit it, but it looks right. Pretty certain that original horn button and associated clip should just drop straight in there.
As for the wheel itself, guess I’ll just ask the company direct what the story is re the small centres.

Wayne, a further thought. The boss which came with my wheel when I bought it is now surplus. The front face and splines are perfect for your wheel, it’s just the rear end that would need a little machining to fit into the column cowl better. It’s not a moto-lita original part and looks a bit rough, but you’re welcome to it if you want.

John, what a great gesture. I would be happy to get the right one and will be glad to pay for and cost you incur.

I think I like the way the small boss hub looks better than the large one. Will keep this in mind for my TR4A.
