Thanks for the photo, Martin, my Crocker´s set up is different from the pic, yours show the magneto version, mine has the smaller distributor. Said cable goes up under the tank, possibly to one of the both ignition keys??????

Yes, I found others as well, because I was inrigued. So the two outside protrusions are for the ingnition wires, one for each cylinder. The center one was linked to another device (some kind of coil ?) either on the front, as in Martin's pic, or at the back of the engine, to a similar device.

Thanks Martin and Hubert, this picture shows my configuration with the distributor. The third wire vanishes somewhere under the tank, like shown in the manual as well.

After airbrushing the frame with Tamiya LP-1 gloss black, I continued with the engine. I added the carburetor and some fuel lines, which are hard to reach later. The engine is more or less finished now and will be mounted into the frame next.

Stunning Rob, presumably this will be fairly heavy when complete? Do they include a stand etc…….

Thank you Phil, I guess, the final weight will be about one kilogram, but the metal engine feels weighty. There are two stands with the kit, a side stand and a rectangular stand for the rear wheel.

The engine really looks the part. Quite the bit  of wiring there. 

Thank you Carl, the wiring is just the beginning. There are more fuel lines, some steering cables, the ignition wiring and the shifting mechanism to be done. Until now, I finished only the later hard to reach lines, manipulating the engine with all the wiring and tubing would be difficult.

Excitement finally granted, Martin :D, you were right. The Crockers were all hand built and not two of them were equal. The ignition system varied with two different types, magneto or distributor type. The ominous third wire leads to a condensor coil, which is shown on your pic. Earlier ´Small tank´versions of the Crocker had that coil behind the engine under the seatpost. The later model had it often hidden under the tank, or like on your pic in front of the engine. I cannot say from my sampled pictures, how the original configuration looked and which are modified later on.
Over on Modelshipworld, there were some very knowledgeful fellows, who added a lot of information in my mirrored build thread.

I achieved some important progress today, marrying the engine and the frame. Luckily casting precision and design is very good and I had only a little wiggling to do, while join the numerous connection points of the engine bearing plates to the engine.
The frame itself needed some bending, to accept the engine, which I did before painting. The cast material is durable but easy to bend an very good to work with, luckily.

At times, it looks as if it was the real deal. Very impressive.

Absolutely a milestone in the build and you have to be all smiles. Some mighty awesome progress. 

Muchas gracias amigos, good plastic motorcycle kits do look great, but what separates the metal kits is the weight of the material, which adds another dimension. Besides, it´s fun to leave the aluminum parts unpainted, the white metal looks the part.

I added the ignition wiring, spark plugs and the mysterious third wire, which leads to the hidden condenser coil, the shift rods and gearbox. The alternator and battery are finished, but only mounted temporary, to determine the length of the wiring. The only "AM" used is the tiny bracket, which holds together the ignition wiring. I fabricated it from tin of a wine bottle cap.
So far no real worries except a wrong aligned part (my fault), which needed to be pried loose. Luckily I was test fitting the following assemblies and noticed it. Electrical wiring is a bit tedious, as there are tiny PE parts to bend, to accept the un-isolated wire, which easily slips out before gluing. You learn to like Tamiya manuals, where they show you the length of the wires, but apart from that, the MFH manual is pretty clear and easy to understand.

What he said Nice!! :unworthy:

Thank you all, the battery / alternator area proved to be very difficult to finish, so far the hardest part of the build. The space is crammed and the alternator needed some wiring and the battery of course too. The wiring consists from normal electric wire and needs very tiny bended PE fittings at the ends, which have to be mounted with equally tiny rivets :icon_eek:. It´s also hard to determine the length of the wires, which needed to be pre fabricated. After a lot of cursing and test fitting, I finally made it. Pictures will follow.

The battery/alternator area was a little bit nightmarish to assemble, with lots of connecting parts, PE brackets and the wiring, which needed to be pre fabricated, because of the tiny PE connection fittings. Somehow, I got it done with a bit of wiggling. 
Adding the pedals on both sides was much simpler affair, luckily and they are now awaiting the footrests.
Until now, there is one thing to remember with that kind of build. Study the manual, examine, where all the parts connect and how, measure the connecting diameters and drill out the corresponding holes and try not to forget any, as they may be impossible too reach later. Sure, test fitting is mandatory as well.

Looking simply brilliant. It's almost impossible at this stage to tell the difference between the kit and the real deal.

Thank you Peter, these MFH kits are something special. The detailing is extremely good and I often ask myself, how they achieve the amount of detail with their white metal casting. Now with the engine almost done, I´m half through the manual, but there are still a lot of challenges to master. There is the spoking of the wheels, the PE chain to build and to airbrush a decent finish onto the tank and mudguards.
I´m really interested, if the motorcycle kits are easier or more difficult to build, than the MFH car kits, but I will find out soon.

Cheers Rob

Quality, precision, care and pride in turning out the best kit possible. I'm sure these factors are part of their design and manufacturing process and a big reason as to why their kits are so brilliant.
