Curl is correct.
I don't tend to forget much.

The part I find so entertaining is that these particular elements of feeding and maintenance of Victorian double rifles are daily bench-gravel for a Barrister, not a gunmaker!!

How appropriate

As we can see here, this community brings out the best of all of us, bits and parts from all of us - from all walks of life -- to better the collective school of thought.

Way to go Curl!
