I had a lucky find a few weeks back on the bay of eees. I'd been reading through old threads here and saw mention of the Towle Pewter Shells. So I did a quick search and found - nothing. I then decided to to look for closed sales and completed listings. Bingo, someone had two completed listings without sale and the last was only two weeks before.

I messaged the seller and asked if they we still available. Yes, and they went back up and I did a buy it now, via my phone, in the middle of a Ikea store! So for $20 + postage I've picked up a nice set of the Towle Pewter Walnut Shell Game.

I ran through my 1 Minute Workout a few times with them on a closeup mat and they handle well with a notch in either side where your finger or thumb can sit. The 1 Minute Workout puts you in a good place to handle shells like these without the Channin Dip. They are heavier, weighing in at 40g.

What a lucky find! Good for you!

Steady hands are still using these shells or moved onto other shells?

These are more of a collectors piece than for regular use. They weigh in a 40g each, not as heavy as the Konigswalder Riesen Set (53g) but still heavier than the School for Scoundrels copper set (32g).
