Lloyd3,
Block letters confirm Suhl.It is a "Place", a gunmaking area close to and in competition with Suhl.It had the reputation for producing lower grade guns than Suhl(likely started by Suhl).They had their own proofhouse(different State)and used the same proofmarks as Suhl;except their "Nitro" was in script letters, whereas Suhls was in block letters.Also they stamped ledger numbers close to the date,whereas Suhl didn't.
