BTW, I've never found a certification label covering a 001xx number. If someone has, I hope I get info on it.

Frame Numbers

Dear All, I would kindly ask if anyone may show pictures of the frame numbers stamped on the steering of the Commandos from 1973 on Thanks for helping!

there was a fella named David Comeau (dyno dave - atlantic green technical services) that was collecting data on commando frames. here is the information he was asking for and i sent --



i'll have to check on the "00126" (batch) number.

EDIT - just checked my frame for a "00126" number on the drive side an found none. since my VIN plate is shifted to the left, it may be hidden under the plate. ??????? my frame seems to be a Mk3 configuration - has brackets for the 75-Mk3 hinged seat.

side note - although my VIN tag states an august 74 build date, the build date/dispatch records i got from andover-norton state september 74 for my bike.

Dyno Dave, from memory, quit colleting info long ago and you can't get to the page anymore.

It is common for the certification label date to not match the dispatch record. I have proof that at least for some years, the label and headstock bearings were on/in the frame before it went on the assembly line.

They changed the format of the dispatch records from time-to-time In your case, no record of "Date off Track" and "Date Tested" so I assume "Date Built" = date ready to be boxed and dispatched ("Date Tested") and "Date Dispatched" = date put on a truck. In some, they used ditto marks and some note. Do you think all in the list you gave are MK2?

not saying this is gospel, and the little i know about assembly line procedures, but things or "like items" are built in batches. this eliminates chance of error, in this case, differences between Mk2 vs Mk2a configurations, which from my understanding, Mk2 bikes were export models and Mk2a, domestic. i would guess all commandos on my list are Mk2 export bikes, and i would go as far as saying all on the list may be the same color. however, speculation on my part. side note - Maylar, a fellow member that has a Mk2 that is nine (9) units from my bike. in this case, our bikes are damn near identical - Mk2, candy apple red, commandos, and assuming export bikes w/ western bars.

You may want to change the link in the Technical Information you maintain (Atlantic Green).

The Atlantic Green website is still available through the existing link and the dynodave tech. files could perhaps return.

The link to the dynodave tech pages has been at the top of the tech. info page for a while, however, I will add the link again below the original atlanticgreen link.

The Mk2As (and Mk1A that preceded it) were built for the European market so not entirely domestic (UK), however, by late '74 the A model was also sold in the US and elsewhere.

And still more Mk2As were sold in the UK and imported to the US, usually by US Servicemembers. My 310311 got to the US that way in 1974.

Interesting thread and I'm glad to know that under the label has been seen, but useless to me - a 00109 with no engine number tells me nothing.

Sorry, didn't notice the new entries - glad to have the data back.
 
My MK 111 has 850 332961 stamped into the headstock . The plate beside it with 4 rivets is stamped 6 75 on one side and stamped 332981 on it as well . Crankcase Left side is 850 332981 . Gearbox is stamped 332981 .
Hope this helps the registry . Mind you this will change next season when I remove the engine to put in my Carrillo rod build engine .

Thanks, every one helps! If the engine has a different serial when you upgrade, please let me know if this engine is RIP and if the bike that the new engine came from is RIP. To me, knowing which bikes are RIP is almost as important and knowing which are still on the road.

My only intention was to point out that the 001xx number can be under the plate.

Could it be 850 332981 (same as the plate, engine and gearbox) as the numbers normally match by this time?

Yes , checked again and the number in question is actually an 8 ( matching ) , the powder coated frame made it look like a 6 .
334226 is my Carrillo rod build engine which I plan to substitute for the present engine after this riding season . It comes from an earlier basket case MK111 that I have in buckets . The original frame is gone , sold when I was poor . I have the original gearbox with the basket case too , it has seen machine work like Roller main shaft drive side bearing and Roller layshaft bearing work done . Both engine and gearbox wrapped in heavy plastic for the future .

I understand and appreciate the proof that they can be hidden under the label and more importantly it verifies that multiple bikes have the same number. About the same time I found the second with 00126. I hope to find more so it will be possible to determine for sure whether they were batch numbers or what.
