Marlin has begun production of the SBL's and GBL's which are available in limited quantities in the US. They are also producing an 1895 SSBL which has a walnut stock, stainless action & bbl. and big loop (BL). The SSBL may not have been released yet but I'm told that they were exhibited at the Shot Show.
Either way, I assume that all the big loops are the same in these variations of the Marlin 1895 and should, therefore, be available as a part..
