Can anyone decode these marks on the LT side case just under the front cylinder? Case and belly numbers are appropriate for a type II WLA.
Thanks.

Does it read "43_40M3" or "43-AOMJ" ?
I can't make much of it..

“1 AOM 3” just below the “43”

AOM probably stands for After Operations Maintenance, the 3 probably means 1943..
But I'm no expert and this could be something entirely different..

Here are similar markings but on a 41WLA.
Upper line looks like 5 43.
Lower line is AOM and another character I cannot determine. Perhaps B?

Thanks Eric.

My 41 WLA is also in the 8000's, so I'm curious about your pic's complete VIN.
Many bikes were serviced before being declared surplus and sold.

Cheers. I'll email you another photo of the left case and also a picture of the BNs.

Looking at a Military acronym dictionary and I’m wondering if AOM stands for Approved for Overseas Movement?
Hoping for some experts to chime in.

Now that's an interesting thought. Here we have a bike that was in Army service early in the war years. Maybe used in a training facility. By early 1943 the numbers of bikes accepted by the Army from H-D might still have been small, so the first US troops sent to England could have been provided with bikes from those already in use. If you look at this video you will see that they were using the 41 models that did not have the oil bath air cleaners.

If these bikes were transferred to overseas duty, then they would have been given a good inspection before being "Approved for Overseas Movement". If that was the case, then this engine could have been inspected in May 1943 (5 43). The "3" after the AOM could indicate the location where the pre-deployment inspection was carried our.

Where did Liberator get his bike from? Does it have AOM on it?

I don't see any 41WLA in this trainingvid; those are all 1940 WLA's and some Scouts (640b) and Chiefs (340).
And one very unfortunate US-model to start with.

My 1941 type II WLA came from the US of A, and besides the VIN had no additional markings on its cases.

No, they were large and included types 1,2 and 3 by early '43.

I bow to the superior knowledge of the experts in identification.

From the case numbers we know it is a type ll, but when in the production of that series was the bike assembled? The engine number should give an indication.

Does anyone disagree with the interpretation of the letters "AOM"?

I'm not familiar with military Acronyms, like I mentioned before.
'AOM' could mean several things, both 'Approved for Overseas Manouvers' and 'After Operation Maintenance' sound reasonable..
And I'm far from an expert; the vid clearly shows too shiny coloured bikes for them to be a 'lusterless flat OD'-41WLA..
Besides, they're all missing a luggagerack and all do have the 6" pancake airfilter..
To me, this screams 1940 WLA..
