Can't read my own prediction table! Actually dates to tail end of 1959, so could still be a 1960 model. Often next year's models started production in the fall of year before.,

This frame #4308 looking at "Kilgariff" site predicts to 1960 and is thus shortly after takeover of Claud Butler by Holdsworthy in 1959 and the Nervex Siere Legere lugs point to this being the Coureur model. The Coureur was built with plain gauge 531. The eBay example the OP links to with the...

Nervex Legere pattern 45 lugs appear to have been used on CB Coureur in first couple Holdsworthy years before switching to more common and later Legere 48 version. See prior post #85.

Re: @Tabbyiab's CB Classique 2742 and dating to c.1963 in Holdsworthy 4D prediction system : - Not seeing an oiler on bottom of BB suggests to me that 2742 has an oiler on top of BB? This points to a build prior to 1965 as this oiler postion change is a consistent finding with Holdworthy frames...

I agree with Dave, looks like a 1963 Classique with a 4D Holdworth number similar to increasing number of Classique frames in data base that have similar Holdsworth serials . Somewhat of a guess, but likely built at Holdworthy factory to Classique specs - thus explaining Holdsworth 4D serial.

Looks to me that's not just a C it is a C followed by a B signifying Claud Butler. Commonly seen on early Holdsworthy Clauds. Here's another example of a 1961Claud Coureur with letters CB near serial (from Dave's database):

Marine06 Any chance you could tell us what serial is? Number should date the frame. Should be on BB. The Sirroco road model with these lugs was only advertised in catalogue for 1951. The same lugs were used on what was renamed the Whirlwind in 1952 and changed the following year. Legend has...

billkilpatrick, Peachy! I believe those are Nervex Legere pattern 45 lugs that were used on CB Coureur in first couple Holdsworthy years before switching to more common and later Legere 48 version for Coureur. http://www.classicrendezvous.com/France/parts/Nervex/nervex_legere_series.htm The...

Parpete, Your frame serial number 1135 does not appear to fit in usual Holdsworthy Claud Butler serial system started in1959 as it would predict to1959 when we know the Classique did not appear in catalogue until 1962 . I suspect what is going on here is that this frame is stamped as some...

FalconSS and Peachy! Frame features with original looking paint and decals certainly must be a Classique which according to catalogue lasted from 62 to 68 inc. No big distinguishing frame features other than paint and kit. There were a lot of CB frames like this built with Prugnat 62S lugs...

Agree, number predicts to 1948. That would be a bronze welded LaQuelda model. Thinking is that the H below serial indicates Bill Hurlow was the builder. He was with Holdsworth during this time. See: http://nkilgariff.com/HoldsModelPages/LaQuelda.htm

Looks like the Holdsworthy 4D custom/branded numbering prediction of 1970 up until 1976 factory move has been revised since last time I looked at data - maybe a year ago? The prior prediction would have had your frame #4615 as being built in 1975. The previous high frame number on Excel was...

Undoubtedly a 1982 model year - the apparent first year for Holdsworth catalogue listing of the Avanti model. Seemingly next year's models often started factory production as early as middle of year before. So... quite conceivable #039295 was a "1982" Avanti actually built in December of 1981...

More accurately number 010392 predicts this Holdsworth Mistral to an Oakfield Road production date of early 1978. In the later 70's the Mistral no longer came in a Super model with its fully sloping Italian style fork crown, reinforced rear brake bridge, bushed brake hole as well as fast back...

I’m quite sure I see a 0 before 10392 making number 010392. The serial system beginning with 0 commenced at time of move to larger factory in 1976. Dave Scrimshaw’s prediction dates your Mistral to 1978,
