In attached photo the left side parts is from their history and the right side parts is now they get.

They have asking here have two different fort type and PIN 1 on the surface marking .

Another attach photo is the X-ray of the different lead-farme.

Can you help to confirm is it same functional to use & the top marking are normal?

Thanks.

Hi Jimmy,

Just checked with team, the left part has a side wall notch close to pin1.

This side wall notch is the indicator for pin1.

Thanks
