Good to have the DBS lowish number in new 6D system at time of Holdsworthy move to new Oakfield Rd facility. This is a period where there is uncertainty re transition of serial systems from 5D to 6D systems.

Similarly important to get more numbers from confusing years 1962 to 1964 when there was an unexplained lapse of original and long lasting 5D serial system to a temporary 4D system.

Likewise c. 1951 is another difficult period as there appears to be a gap of approximately 1,400 frames with not an example from numbers 13615 to 15094. (Presently deduced to be during 1951.)

Numbers with good history around these periods hopefully will surface.

I've just picked up a Mistral, but with 1/2 chromed stays and 1/2 chromed forks, which seems a little unusual as most of the Mistrals I've seen have no chrome, unless they're Supers, but this one has the normal mistral fork crown not the fully sloping nor full chrome fork. Possibly a custom finish order?

Number on the BB appears to be 1172, which would suggest a '71 or '72 model which seems to fit with the rest of the bits (and the Reynolds transfer version), but I'll need to drop the fork to confirm number as it's a little hard to be sure from the BB number.

It's a bit grubby and I'm short of time at the moment but will clean it up over the next few weeks and get some pics up. Probably going for a full strip and rebuild approach on this one as I have plans for a 700c fat-tyre light tourer to compliment my Mercian KOM :-D

Thanks for the info. Yes these four digit numbers seen in the 70's are a bit unclear, currently the charts are set up suggesting that the 1st digit signifies the year witin the decade, but there is not a lot of info to back that up.
