What manufacture are these early Struts?

[tcsracing1]

Pulled these from my 67S.

Would these be correct?

[doigthom]

To be correct you should have Koni for a Coupe and Boge for a Targa

strut looks correct for a 67S coupe(not targa)
the mounting plate for the calippers is homemade???

[Jim Breazeale]

I'm stumped

It appears to have a Boge logo in the casting but the strut is stepped like a Koni, but is isn't a Koni.
The caliper mount is a crude, but effective, homemade part.

Regards

the home made calliper mount was made by previous owner to fit 1972 S callipers...

I now have the correct brackets and callipers to go back on, however the strut bases puzzle me....

Gled...
That is a thing of beauty.

here are some more pics of my struts.
anybody know what they may or may not be?
They have a date on them stating 66

should i use them for my 67S? What say you?

[tcsracing1]

anybody know what the logo is for?

The logo could be that from the forging company that made the stub axle component.

I am sure that the later struts were made using the same forgings regardless of the strut supplier.

I believe Porsche organised the forging manufacture and supplied 'free issue' parts to either Koni, Boge or Bilstein who made the damper and the casing.

This would save cost in terms of tooling and help with volume discounts in terms of production.

The logo may be a 'red herring' in terms of the strut manufacturer and at some stage the logo may have been removed as I have never seen this on any other SWB Strut
