There is a very common Selmer neck that works well on these and is also adjustable/tunable. I think it is a Selmer 9 BBb neck, and I almost bought one for My Pedler 201A because the original neck has a very narrow socket. Finally I found a Geo. M. Bundy #3 vintage piece that works fantastic. The fit is still very tight. So if you can't find an original neck, check out the Selmer 9 necks that pop up here.
It sounds to me like your bell is similar to the material of mine, which the catalog states is nickel-silver on the 201 types. There might have been some silver-plated Custom built models. There are certainly a good many soprano Pedlers with silver plate. That's a small matter compared to the wood quality and the key work. The wood on these is superior;- if it is in good shape, you have something special. Mine has a good number of cosmetic defects, filled screw holes from old end-pin hardware and the strap lugs have been re set and the old holes are also filled. Even with a few flaws, the grain and color of the wood is gorgeous;- and so is the sound.
I think the quality of these Pedlers, either the 201 or the Custom-Built is such that either merits restoration if there are no tragic damages. The bell on mine looks to be original with braces that match the neck braces and similar sockets, but for some reason;- no engraving? Such is as it goes with vintage instruments. See if you can snag a Selmer 9 neck before you give up on it.
