Huge Op Shop Haul

I have been asking around about preserving equipment at all my local op shops for a while now and had left my details with a couple of them.  The other day I got a call to say that some had come in from a deceased estate and would I still be interested as they had been in the shed gathering dust in the shed for many years.
I let them know that I was still interested and would be in the next day.

Well what a score look at what I got, a preserving unit, 2 crates of jars and accessories.

The haul
PS the kitchen Aid is mine and was not from the op shop

So here is what I got:
A small preserving unit with the front plug missing.  Well I assume that is what is missing, does anyone know?

See the little hole in the front

 There were a whole lot of rings stored in cornflour and they look to be in perfect condition.  Does anyone know why they would be stored this way?

Rubber rings stored in cornflour, well I assume that white
powder is cornflour.
If I am not back in a week you will know that it was not.

 I guess this is an indication of when they were last used.

Jars with a good layer of dust.

Sorry about the side ways picture.  But there was a stack of clips (about 30), lids (8 that were ok to keep), tongs and a thermometer.

So I did some calculations about what I got and the cost of buying new:

Jars
14 x Number 27 (800 ml) =  Not sure. I cannot find them new so perhaps this size has been deleted.
9 x Number 20 (600 ml) = $28 pack of 6
12 x Number 31 (1 litre) = $34 pack of 6

Clips = $15 pack of 12
Tongs = $16.50
Thermometer = $22
Rings = $4.50 pack of 12
Lids = $15.95 Pack of 12

Approximate cost = Over $220 new

And that is NOT including the preserving unit.

So what did I pay....

$20 for the lot!!!

I will need to pay to have the preserving unit electrically tested but there is no urgency as I have my stove top preserver which is much bigger than the op shop one.

I now have stacks of jars and just need to sort out some lids for the size 31 jars.  Then I will be preserving like a mad woman.
