Ahh yes, I see you have most of the range there Dave.
Starting with the small/medium engineer's adjustment model, and moving upwards in regular increments.
I actually have one, complete with 40mm gal pipe handle (so it doesn't splinter)
for large to medium/big adjustments.
I got it from a kind fellow who left in my shop (when I had one-shop that is) after he/they broke in for the 3rd time in 6 months.
I did actually put it on display above the counter, with a note attached asking for the owner to come and claim it.
Strangely no-one took up the offer, so I kept it...........as a memento of our fun together
