There are actually four classic steampunk gas mask designs available here. We have perfect confidence that one of them fits the plans for battle (or whatever) you carry with you.
Shipping of this item is free, as is our excellent custom. We ask you to wait 12-20 days for delivery, please.
And as always, if your travel plans include rail, or even if they don't, we hope you'll consider Steampunk Union Station.
We'll be here, 100% (satisfaction) guaranteed.
