Lynn,
Here's a picture of my slide, I'm not terribly
happy with it thus far.
For those not familiar with slides, on a single
slide the half moon gives more of a linier opening than a flat ended slide. Mine
is similar to the old Posa and Aero Carb with no fuel reservoir - fuel is
supplied with a slight fuel pressure.
I'm also a fan of the flat (back) fuel needle like
the Aero Carb. However I like the idea of having an adjustable needle/ leaning
capability, so I used a needle on a spring connected to a threaded driver, which
also acted as the throttle cable.
It's a good idea, but I'm afraid my machining
skills are a tad less than desirable. Although it's easy to make a slide,
making it all work will, without binding and sliding easily, is another
story.

Here is a page with lots of Lucas links.
I had a few apart years ago, because they get dirty inside. I think all
of the rollers and spacers were loose and had to be stuck back in place with a
bit of grease. They ran on hard strips in a an aluminum casting. They were
trouble free in operation as was the whole system. Remarkable for anything
Lucas.
Probably because no electricity is involved. Kinsler still makes parts
for the pumps and whole new pumps. The Kinsler stuff is for CanAm car and 5000
car restorations. Modern sprint cars usually use Hilborn. No slide throttles
involved.
Here is a picture of a slide set for a Cosworth engine. My first
experience was with a Brian Hart Ford Twin Cam engine. It blew up when one of
the precision British aluminum cast heads colapsed and dropped a piece of
intake runner into a cylinder. I sold the injection to a guy in NewZealand.
You might find one at a swap meet cheap if the seller has no idea what it is.
Racing Beat used to build a two hole slide set for their engines. I wouldn't
be shocked to find out they had one laying around
The electric pump is just to start the engine. The belt driven pump is
for racing, and the electric pump can take over if a belt breaks or flys off.
