Blue numbers stenciled in my inland stock??
I picked up a 300,000K series Inland with what looks like all original inland parts. When I removed everthing to check part stamps I notices blue numbers stenciled or stamped on the inside of the stock below the barrel. To me, it looks like 144-3 or 144 3. Anyone know what it is for or if it can be read as something useful? To me a date reference would make the most sense but do not want to read too far into it.
Thanks
Steve
