"The Derrington ones" & "The Cooper ones" are exactly the same wheel.

M

Just what have I started! This has turned into a very interesting thread indeed. I had the wheels lightly blasted at the weekend and have posted pictures below, there are no signs of any markings on the wheels, apart from numbers stamped on the underside of the wheel each wheel, showing a stamped number 1,2,3,4 etc that is all one can see. Apart from that the wheels are in good condition, with some small areas showing signs of pourus casting. It is also interesting to hear what Nick Vortz had to say with regard to these wheels and I do agree with him they must have been done by a small outfit with limited resources, however one thing baffles me, why go to all the trouble of casting such items in such a small batch? When others where available from the likes of Cooper Car Co, Derrington, Vortz. Surely it could not have been cheap to cast these wheels. I really do hope we get to the bottom of this, as it seems i am not the only one whom is intrigued by these wheels. Keep the information flowing, someone somewhere must know who made these. On a side note, what lovely looking wheels rosepetals are!!

Cheers,

Simon

I have had some JA Pearce mag alloys and some pure mag minilites. These are the colour of a mostly aluminium alloy. The fact that they show pumice style holes means they were cast by a monkey.

These need a density calculation done of them using a half decent balance and a watertight container you can get the wheel in and H20 = 1g/ml

Maybe I´ve been to fast with ruling the Danish rims out, but I never read or heard about Danish rosepetals, except the 6x10" ones by Rytter before... Does any one have any information about other Danish makes?

There were some 4.75" ones cast in Denmark, a friend has a set on his Mk 2 S and there was a set for sale at the Danish IMM in 2007. They are certainly not magnesium as they are much heavier than the originals.

According to the owner "I recall an old photo of Erik Høyers first race Mini where Erik is stood next to the car on the old Roskilde Ring Circuit, circa 1965 - here the Mini racer is equipped with what looks to be the 4,75" Ole Rytter Rosepetals.

My thinking is that Erik Høyer and his mechanic Poul Heikendorff had the wheels copied from the original rosepetals manufactured in the UK."

Judging by the number of small inclusions & voids in the wheels I am fairly sure that these examples were not cast on a commercial basis.

Was out "shopping" yesterday .

Here is what the 6x10 look like in original spec.

Nice purchase!

Cool wheels JC. Don't know how I missed this tread. Here is some photo of one of my mag rosepetals which might help ID the wheels for Simon. I reckon Simons are genuine ccc mag rosepetals!

Very nice Jens, did you buy 4 and what are they going on?

I still don't think Simon's wheels are original CCC mag Rosepetals.

Compared to the original wheel below there are differences in the composition of the alloy. The one below is magnesium. Also there are subtle differences with the centre boss hole. On CCC ones the internal bore is stepped quite close to the outer face whereas Simon's appear to be a uniform internal diameter from front to back.


They are very close though.

The mystery continues

I agree with ´S´type & Simon776 on this. The wheels you have Simon are 100% identical in the poor casting to the 6X10" on my car.
So they might be the same type .

Thanks guys

I had known about them since August 2014, where I met the seller.
He saw my car, and said he had 2 wheels like that.
I saved them from ending on a garage wall, as airhose parking.

steve1071 wrote: did you buy 4 and what are they going on?

No Steve, he only had 2.
I will use both on the WP/JanSpeed Mini, together with the 2 best ones, I have on the car, and make a matching spare wheel.

Interesting request for info about wheels on a new TMF forum post, see link below........?

Sounds like a very interesting car hope he post some more Pictures.

I have 5 of 4.5x10 and 2 6x10 of the Danish Ole rytter wheels, and a set of genuine 4.5 magnesium.

The Danish ones are very heavy, and the magnesium very corroded.

Where did you get yours from Simon ?, the stainless wheelnuts look exactly like a set i did some 20 years ago

So its on, the wheels I had on the car, are now getting their edges & centers skimmed in a Lathe.

Next they will be polished, and the spokes painted Black.

Photographs of period race car in my garage. Rosepetal wheels stamped Cooper Car Co but don't know what age they are. Would they be mid sixties?

Those are Vortz wheels, with the CCC stamping mid 80's to early 90's, it looks like someone's enlarged the centre hole to get them on a balancer

Thanks very much for that information much appreciated.
