You are right, some of the early Anglo Indian Taplins were from parts which were cast in UK, as Kumars bought the tooling, stock and rights. That's the reason you see made in England on your Indian Taplin.

If you ever wish to part with any of the Taplins you have consider me in line

Hi Fiery,
Looking forward to seeing it running!
I assume it doesn't have a serial number... you would have mentioned it...
Does the case have the British patent number stamped on it? If so, I should think you're both probably right about it being assembled in India at least using an original crankcase...
When Taplin stopped production in the UK, there was quite a large reserve of unused parts (that's where Arne Hende's 15cc engines came from, via Mike Clanford and John Goodall). But as the Mk III was going to be made in India, it would seem reasonable to assume that remaining parts for the Mk III were sent there.

PS: Manish, look at it this way... you're probably at least 20 or 30 years younger than me... so it's just a case of hanging around long enough...

I own one TT, and it's a "green one" (7 cc)

It started its life as an 8 cc marine version, though.
About 30 years ago I swapped the "upper parts" with another TT owner, badly needing the flywheel and w/c cylinder/piston units for a boat project....all parts in good shape, both ways.... The green prop driver & spinner nut are "NOS" parts.

The non-anodized spinner nut & prop driver below, were custom made for me by Kid Janacek (great guy, formerly peripherally involved in the DAMO project, etc....), as I initially (while still watercooled), wished to test run with an airscrew, thus preventing a "revving to death" situation with a flywheel.....
As I won't use these parts any more.....does anyone need them....?

As I understand it, you should now have a 7cc engine. My own Mk I (green) also started life as a boat engine, but was converted to aero. Super runners, all of them.

I have several original smaller Taplins (4 to be precise), they're much nicer in every way.
Earl, if you had just the normal "Aurora Taplin Twin", they're 8cc, not 5.
I could have sworn I had a .30 size Aurora made Taplin RC twin. Isn't that about 5cc? I bought it from Hobby Lobby way back then circa 1980-81. When Hobby Lobby still sold more exotic items to the modellers. I don't think it was the bigger one. But maybe my memory is going bad you are likely correct.

Taplin Twin Ser. III 2012 issue

For those who want a Taplin Twin, Aurora has just built a limited number, and are about to release them.

Price is US$350.00

There will only be a few. Original intentions were to build 50, but there may be as few as 12 available. I am told there will be no more.

If anyone is interested they should email Aurora, attn. Mr. Rishi Kumar.

email address: aurora_cal@yahoo.com

I've one on order with Rishi.
The payment system with the bank might be the stumbling block, as the bank in India doesn't know who the payment is for!
Here's hoping Rishi got his money.
Unfortunately, PayPal is not acceptable, which is too bad as it would make life so much simpler in this situation.

I have ordered one as well.

I paid in Australian dollars. Mr Kumar has acknowledged receipt.

Paying by international bank telegraphic transfer is a pain. PayPal was not available.

The engine should arrive in August. It will be interesting to see the quality.

I made my K600 run. A sent a copy of the youtube video to Mr Kumar. He was delighted.

I am replacing the ball races. The rear was lumpy and the front open race leaked fuel like a sieve. A sealed front race will sort that.

Does anyone know if the area joining the two cylinders (TT) together is a weld or a brazed joint? My 3.5 green head has an exhaust extension that appears to be soldered. I wonder how the overall process kept the cylinders from warping or becoming distorted ?

I'm no kind of "engineer" but I've just had a look and I don't think it can be a weld. Looks like very neat brazed joins.

I am sure it is brazed. Aurora's were having difficulty sourcing the right material for the last batch of TT's planned.

I asked the importer in the UK for one, so maybe I'll get lucky, but with only 12 available, they may be gone before even the UK importer gets them.

Yeah they braze the intake manifold onto the cylinders. Very neatly done too.

I don't know, but from the picture, it looks like silver solder on the manifold connection.
