Where from if you don't mind me asking?
I found it on eBay. Watched it for days hoping to be the winning bidder. I was shocked when got it the price I did; pretty sure I would pay that much just to buy all the springs.
The Heidi Shop was selling them a few years ago, but last couple times I looked they didn't have them in stock.
I have one as well, they are fantastic. No clue how many springs I have replaced through the years for family, friends or SAKs I bought cheap with missing or broken springs.
I bought one a few years back from Heinnie Haynes in Wales, UK - certainly makes spring changing a breeze!
I can't believe how easy it is! Every way I tried in the past was rather frustrating. I always felt like I needed a third hand. The anvil clamp is that third hand!
