Obscure resistor, what is it?

What is this, the big resistor?

That looks like a 1/2W carbon composition resistor.

if I was to guess it is a 6.8 ohm 1 or 2 watt carbon composition (or film) resistor 5% and it looks like it is cracked so I bet it is open.

does the resistor have smooth rounded edges or is it built like a perfect tube with sharp edges.

looks like a television chassis

I'm a bit puzzled by the rings: Blue, Silver, Gold, Black, Brown.

Or it is Brown, Black, Gold Silver Blue

which is 10 x 0.1 5% = 1R 5%, but I dont know what Blue is!

I think I have the answer. It's a fusible resistor

1.0 ohms, 10%, fusing characteristics 12 times

That just looks like a 1W or 2W Allen-Bradley resistor. AB resistors have that brown cylindrical body.

Here are some examples:

blue silver for the first two digits does not make sense.
It appears to be brown (1) black (0) gold ( *0.1) silver (10%).
I cannot explain the blue banding. temp coef (unlikely) fusible (don't know).
I would guess a carbon composition 1r0+-10% 1W

Correct. I have exactly the same one in my hands right now.
