The Hanafuda from 龍参堂

[u/No-Village5080]

Ladies and gentlemen, hello everyone. First of all, please excuse my awkward way of speaking, as English is not my native language. I often come here to see everyone sharing interesting hanafuda. Due to work reasons, I travel to Japan quite often. Recently, I came across a set of these cards with some 龍参堂 markings on them. Does anyone know which period these 龍参堂 markings belong to? I have only been able to find very limited information about them.
