Does any one have any photos of the barrel channel of the M03 model?

I am particularly interested in both the lock up mechanism of the M03 ie how the barrel is attached to the stock/action ... and also what metal fittings are in the stock itself, particularly the barrel attachment.

I believe there is an alloy block in the fore end stock to which the barrel attaches by way of two screws? Is this correct?

Is this alloy block attached to the action ie solid with the action, or attached to the stock?

Thanks for any comments and especially photos.
