Pics continued. You may notice that unlike most other engines, there is a seperate insert on the head that carries the plug. To open the insert one would need specialist tool with prongs to fit in those depressions on the insert.   

This engine left the factory in 2002, you can see the gasket on the muffler joint. When OS came up with the AX series and the Power box mufflers the muflers had severe leakage from the joint, till they started supplying them with an O ring gasket. 
The supplied instructions, dimensions, blown up parts list, and specs

And finally a sealed and signed gurantee

I had earlier shown my Taplin MK III that came as an aero version with parts to convert to Marine.
Here are some pictures of another Taplin, this time a MK II Marine.
You can observe the difference in the way the head is fixed to the case. This one has bolts down the head securing it to the case.
The engine is yet to reach Indian shores, but is in a safe pair of hands.
Enjoy the pictures

manish

you could open a RC Engine museum !! is it on your mind ?

No not on my mind
Actually there are some very desirable ones going under the hammer, and the prices at these auctions are reasonable when compared to ebay etc. If only there was a way to bid

Pradu,
Check your inbox

sorry manish sir... but i picked them up. 

Ahh ok, Good acquisition I must say

indeed... awesome books..

the radio controlled book has the technology that is way beyond yesteryears.. it has all the vacuum tubes , motor escapements and mechanical movements for the control surface movements.

Time to update some more,
this time we have a repro diesel engine, no box or papers but un run.
An MP Jet 040.
For more information you can visit   http://www.mpjet.info/news/78-mpjet/82-mp-jet-040-pb-classic-diesel
Very Mills inspired and piston ported like the Mills.
What better design than a Vic Smeed one to put this beauty in, and let the large prop do the hauling at slowwww speed.
Enjoy the pictures   

One  also missing Diesel frog from uk

Re Frog, had one long back a red head 1.5cc long back, in a fit of stupidity sold it.
And not just the frog there are so many of them that are missing

P.S Or was that a green or blue head Frog (can't recall clearly)

Yes  with red head and twin ball bearing .very good engine. I have two but not in very good condition.

Next on the list is a NIB OS 61 SF ABC (P)
That implies, the engine is an ABC configuration and equipped with an integral pump.
Just look at the sheaf of literature provided with the engine and best of all, the mounting template, this was so handy, but to the cost cutting measures, OS had to stop supplying this template.
The Carb is still packed, and oh! do notice the nice touch of plastic blanking plug on the carb spigot

Pictures continued

Concluding batch

Next on the list would be an engine meant for this muffler 

The next engine(muffler pictures posted earlier) is fairly ordinary. An OS 200 four stroke. So no explanations required.
The engine was bought used, original owner having used castor based fuel had locked up the engine solid. 5 minutes with a heat gun had the parts freed, some 2T down the openings and propeller attached to turn it over had the engine and parts freed up nice and proper.

  Is there ever an end to this Endless list Captain  

Oh! how I wish there was a way to end this insanity   

Can I relive this engine?

Yes send it to me and you will be relived of it

brazing welding is solution.
