Hello, first of all I would like to apologise for any grammar errors etc. since English is not my first language. Recently I've become curator of Tanegashima which is subject of the help I'm seeking, posted below links are to the images of signatures and particular elements of the gun. I've been lurking for some time, but only today managed to disassemble the barrel from the stock and decided to ask for help.
I've forgot to take picture of the whole gun but can add later. There was no signature on the bedding of the stock, ramrod is unfortunately stuck in the bedding/stock and lost it's stamp (was possibly made from metal), barrel has caliber of 14,54 mm.
From what I gathered the kamon is of Hachisuka clan, and gun can be a combination of two different craftsmen (Sakai/Kunitomo group? Signature will definitely disprove my speculations).
Any help is appreciated, gun is very beautiful and I would like to learn more about it.
Edit: I've added images directly into the post, unfortunatly imgur does not let me copy link to whole folder additionally.
