Difficulty identifying FPL and prototype features

Hi - I'm hoping someone with much better prototype knowledge the me will be able to look at the image below and help with identifying the following so my recreation is as accurate as possible:

There are 2 linkages to the toe from the rodding but I can't tell if one goes to a FPL and the other to a stretcher or if they both go to 2 different stretchers - what do you think / what would be normal?

It looks like there is a base plate on the timber with the switch toes on (you can just see it poking out and under the slide chair) - would that be correct looking at the photo (1930s / SR), have I seen that correctly?

It also looks like there are 3 extended timbers to fix the cranks to (2 longer and 1 slightly longer), have I identified that correctly or are they separate to the turnout timbers?

Thanks for any help and apologies for any mistakes with terminology.

The one nearest to the camera goes to the front stretcher and the further rod goes to the FPL.

Hi James,

The longer rod is for the Facing Points Lock. The lock plunger engages one of two slots in the lock stretcher.

The shorter rod is the drive rod connected to the first stretcher bar.

Yes, the rodding cranks are fixed on extended timbers. There is an additional crank in the "4-foot" for the lock plunger.

You can see the end of the sole plate on the toe timber, and the rib welded on it to prevent any gauge-spread of the chairs.

There are some photos and diagrams of all this, about half-way down this page:

One of the photos shows the sole plate and rib very clearly.

cheers,

Martin.
