The listing said W. Germany, one of the out of focus pictures showed the EF stamp on the section. The rounded ink view windows was another confirmation of an original barrel. The piston knob end showed the L mark very clearly. The only doubt was if the clip was correct with the inserted ball. One of the pictures hinted at the characteristic chamfer that such clips have.
The BIN price was reasonable for an early Lamy2000, but anyway I decided to wait 24hrs and if no one had bought it by then, I would buy. The time passed, no one had bought so I bought and the pen arrived yesterday in India.
as shown it was full of dried ink, a well loved pen. The pen is now completely overhauled and pending photography, all features correct including an 18K nib and thankfully no section or cap cracks.
