I am considering a suspension upgrade on my BSA Victor.
I have two forks and a couple of triple trees available, but I need some help identifying the parts (and figure out what would work best) as there are basically no stamps or engravings to be found. All of them are 35 mm.

Ceriani/Betor? - 20.00/19.65 mm. stem.

Marzocchi - 24.85/24.30 mm. stem.

Ceriani/Betor? - 24.90/22.60 mm. stem.

CZ - 26.00/24.95 mm. stem.

The forks in the first pic are Cerianis, probably from a Penton, can't tell much from the Marzocchi pics, but that's what the triples are, so probably right as well. The first set of triples only that you have are Bultaco. It depends upon the intended usage to give you any recommendation as to what to use, but the Bultaco clamps would be close to the same offset as the original BSA, if that is what you're after. Personally, I have a similar project, and I am using the Bultaco clamps with Husqvarna forks as I want to approximate the stability of the original, but I want the lighter weight of the magnesium sliders the Huskys offer. The Marzocchis might be magnesium, but it would be hard to tell from a picture.

Thank you for taking the time to answer - that was very helpful!
MX origin would make sense, as all of the parts came as spares with a couple of Rickman and Cheney BSA's.

My plans for the Victor is a mild bump in power and 70's-era performance modifications: Upgraded fork and rear shocks, lightweight wheels, performance brakes, ace bar or clip-on's.
The goal is an entertaining classic, modified as they would do it back then, but without cutting or welding anything. It has some patina but is otherwise complete and 100% original - no need to ruin that with mods that can't be reversed smile

The problem you'll run into is the fork stop on the frame will interfere with the clamps. If you don't want to cut and weld, you could just take the stock clamps and have them machined out to 35mm. Dick Mann does this on the bikes he builds with good effect. If you're interested in this mod, let me know and I can email you some pics of some modded clamps.
