Hmm. B&L made Compound shutters under licence. Goerz American is more likely to have used B&L shutters than to have imported.

Abruzzi, just send your shutter to Grimes and pay their price for a retaining ring.

That’s what I was planning, but I was hoping to buy the retaining ring from him without having to ship shutter both ways.
