Sadakiyo Signed Silver Fuchi

[kotachi]

Hi Everyone,

I am trying to find out more about a silver fuchi with the signature Sadakiyo 貞精 I bought a while back. It has a dragon in the clouds carved in katakiri bori style. The seller said it was Yokoya school. 
I thought it was gimei and just liked the work/price plus that it was silver. I recently stumbled across a matching theme and signature on a tsuba on eBay.

No details and a big markup, so after searching around I found the same one on a Japanese site (on sale too!).

And using google translate it also mentions Yokoya. Looking at Sesko genealogies for this school the only name that is even close is Terkiyo 英精 of whom there were three generations. Does anyone have any info on this smith? Could this be a real Yokoya school guy? I guess I am now hopeful it could be student of Terukiyo that inherited the Kiyo character but please let me know if you think I’m going in the wrong direction. Thank you for any thoughts.
