From another thread, my Kirk Precision in front of the former Kirk factory:
I used to know/ride with, two brothers who both had Kirks
One had the roadie, the other the MTB
Your bike in front of something different...

Wow that Kirk is a great looking build, what/where was the the other thread it was mentioned on? I'd like to read more.
What's your verdict on the L-shaped cranks, can you notice any different riding characteristics to standard ones? Wasn't it supposed to reduce or eliminate the dead-spot at the 12 o'clock/6 o'clock positions while pedalling or something? Not that I can say I've ever really noticed having a dead-spot on the pedal stroke, so I always assumed it was just something cooked up by the marketing department, and if it really was beneficial I would have expected it to have caught on instead of disappearing.
They look good with the convention defying frame anyway, top work I like it

Thanks! The original thread was here, where having realised I was walking backwards into a collection of Essex-built bikes, I wanted to add a KP to the stable.
The L-shaped cranks make absolutely no physical difference whatsoever to the pedal stroke.
They were indeed meant to eliminate the dead spot at 12 o'clock, but were purest 1980s marketing fluff, making it appear that when your foot is at 12 o'clock the force is somehow being applied at a different angle. In reality, it's exactly the same lever as a straight crank, but follows a more circuitous path to the fulcrum. (If the cranks were made from 350mm diameter aluminium disks or S-shapes or Z shapes, it would make no difference to the pedal's axle position in relation to the fulcrum.) I dare say they had a psychosomatic effect though - if they feel faster, they probably make you go faster. Imagine what would happen if you fitted them on a red bike!Interestingly, when I picked the bike up, it had oval Shimano Biopace cranks, which actually did make a difference (albeit a different difference to the modern Q-rings, which are 90-degrees rotated compared to the earlier Biopace). As a result of being not just different but both different and effective, they had to go!

@Specialeyes thanks very much, excellent stuff. 
Loving the way you roll with that build, and riding out to the bikes roots too, top work all round

A spider web covered hedgerow, somewhere in Cumbria. The area covered is much larger than it looks in the pic.

Edit: not sure why the pic didn't turn up fully at the first attempt..
Apparently not spider web, but some kind of moth iirc.
I bow to your superior knowledge..
I couldn't see what was living in it, so I kinda guessed.

It was @Rickshaw Phil that told me
I'll bow to his superior knowledge instead, then
