I'm conflicted.
Part of me, the same part of me that takes in half dead stray cats, wants to take it home and bring it back to life.
However part of me is screaming "No, been there, done that, have the tee shirt, and can't afford another one." It's one thing to buy a beater that's airworthy or close to airworthy that you can fly and enjoy while you slowly upgrade it in small bites as time and funds allow. It something else entirely to start so far behind the power curve that you might not ever be able to climb out. I draw the line at bringing it home on a trailer. I did that ONCE.
As is, it doesn't have the bare minimum of required instrumentation to fly, even if the engine and airframe were basically sound and you got a ferry permit for it to get it to where ever you plan to work on it.
You can get by on a handheld radio or less, but to legally fly it VFR you need some minimum instrumentation per the A TOMATO FLAMES mnemonic:
A –
Airspeed Indicator (properly marked for the aircraft per the aircraft's POH)
T – Tachometer (properly marked for the aircraft, which it looks like you have)
O – Oil Temperature Gauge (looks like you have it)
M – Manifold Pressure Gauge (not applicable to a fixed pitch C150)
A –
Altimeter
T – Temperature Gauge (CHT) (looks like you have it)
O – Oil Pressure Gauge (looks like you have it)
F – Fuel Gauges (looks like you have them)
L – Landing Gear Position Indicator (Not applicable to a C150)
A – Anti Collision Lights (Not applicable as it only applies to small aircraft certified after March 11, 1996)
M –
Magnetic Compass
E –
Emergency Locator Transmitter (ELT) (I'm guessing it's missing, or at least needs a new battery)
S –
Seat Belts (just a guess that they're gone as well)
You also need all the placards specified in the POH, although you can do them with crayon on sticky notes if you want, so that's not a big ticket item in the short term.
Getting the missing bits re-installed is going to take a fair chunk of change, particularly the pitot static instruments.
There's no right or wrong about buying it or not buying it, just go in with your eyes wide open and fully understand what you are taking on. And, when you go to look at it, go willing to walk away from it if you find serious issues like corrosion in the wings or fuselage, an unserviceable propeller, or an engine that's not worth anything more than a core and/or may have suffered a sudden stoppage and needs a complete tear down.
