Wanted: Triumph 2-piece crank

Looking for 2 2-piece Triumph cranks, which are proper for D2 forward. I do have a couple of cast cranks for trade or will purchase outright.

Just a question, what is a 2-piece crank? Picture would be great.

I believe he is referring to the crank construction where the shaft and crank throw are two separate pieces that were joined together, versus a crank made from a casting.

Like this...

Got it, just never heard it called that way.
Is there any rhyme or reason for which crank is used on what model?

I looked at some of mine and
Fireside A, (3) Standard D's, Home F, Home B, Triumph F, Opera - All have 2 piece cranks
Fireside B, Triumph B, Standard F - All with cast cranks.

Inquiring minds, etc, etc
