Are you really serious? I wonder what you consider a 'not too much' price for one of the jeeps you are into?
Be very careful if you are planning on flying it legally. The price of an aircraft is primarily based on the remaining life of it timed components and general condition. The airframe, transmission, gear boxes, anti-torque rotor blades, main rotor blades, etc have time limits. There have been a series of required safety modifications ** called AD s airworthiness directives} and again have all these been applied and logged?
One of many issues you need to consider is this: The early 47s had solid wood rotor blades, and over time these could cause problems, the newer ones used aluminum. If you look up the price of new rotor blades - search BELL 47 -23 METAL MAIN ROTOR BLADES on e b ay now and you can find a set for 47,000$.
Now as for engines - a Franklin was original in the early models so check the hours remaining before a rebuild is needed and price out one of these new or rebuilt. Start thinking about $17,000 on up for the Polish ones.
The 47 has over the years many variants so which one is the one you are looking at?
So I am amused by your 'he doesn't want too much money for it' - what in world does that mean?
If you are really serious and want a flying machine, and not a museum display, you should send an Bell 47 expert mechanic to inspect the aircraft in detail, fly it, and pay him for his time. The first thing he will do is to look at the engine and airframe log books in detail. No log books and all you have is a grounded display item.
