Anyone recognise these markings on a 70's MFI pump?

My MFI pump has recognisable designations (0408126021) plus a serial number. It also has a stamp on the plate underneath the serial number with a small triangle with the letters GAH in it and 588R after the triangle.

Does this mean anything to anyone?

Thanks
Graham

That's the Bosch part number. It indicates you have a 72-73 2.4S pump, Porsche # 91111025300.

Can you post a photo ?

Sounds like a mark made after a rebuild or recalibration
