WTB Looking for some Gillette bits and pieces

Over the past few weeks, I've picked up a couple of razor parts lots and would like to round out some of the odd bits into complete razors. (This would be for personal use and/or PIFs.)

First, I have a pair of OT baseplates, a brass/gold one from 1917 and a nickel one from 1919 (with a refurb serial number) that I'd like to find caps for. Am I correct in assuming that both would have come with thin caps?

Second, I have the core (baseplate, neck, and tube) from a Criterion New Deluxe. I'd really like to find an appropriate cap and screw for this.

Finally, I recently received a Tuckaway razor as part of a PIF (just the razor). I'd like to find a matching case for it. Condition is not an issue as long as it is basically restorable.

Thanks...
