I never really chased the Liberty models to collect them all, but instead went after the ones I considered rare/scarce/unusual (or whatever I stumbled onto
).
For Service Sixes, I have the "GH-34" with the Machined heavy barrel (MB) that I posted in another thread discussing those few guns with the early heavy barrels and the weird muzzle crown on the blue (non-Liberty) version. The unusual "GH" catalog number designation ended up not being used long, instead reverting to the GF nomenclature with the H as a modifier after the caliber/barrel codes.
Also for Service Sixes, I have a GF-84 which is the same gun but in .38 Spl and with the standard barrel and normal catalog number.
Other Liberty "-Six" revolvers I have are:
RDA-82 (blue .38 Spl 2.75" Security Six, noted as the only one known)
GA-84 (stainless .38 Spl 4" Security Six factory second "S" gun, noted as the only one known)
GA-34 (stainless .357 Mag 4" Security Six)
GA-36 (stainless .357 Mag 6" Security Six)
SS-82 (blue .38 Spl 2.75" Speed Six)
GS-84 (stainless .38 Spl 4" Speed Six, noted as rare)
GS-34 (stainless .357 Mag 4" Speed Six)
SS-34 (blue .357 Mag 4" Speed Six)
