I had this mdl.66--(2K83710) for a long time but just notice it a had a letter
L on the face of the cyl.any idea what it means?

The prevailing theory is this was stamped to indicate it is a stainless steel part (and not to blue or nickel plate it ).

There is another letter commonly stamped there for the same reason but I can't recall which one. Not anything logical like S, however...

On the Model 28 Highway Patrolman, there is an H stamped on the cylinder face, so that the finish shop gave it the satin blue finish instead of the bright blue that would go on the otherwise identical Model 27 cylinder.

Incidentally, on K frame dash one cylinders, an L was stamped to indicate the extractor rod assembly used left hand threads - a change from the previous right hand thread assembly.

You are probably right on the early 66,i also have 2 1/2 in.66-1, 4in.66-1.
6in. 66-- no l stamped on the cyl.face.

Keep in mind that my reference was to models made back before the thread change on the extractor rod. The Model 66 was introduced in 1970, long after that change had been implemented. No Model 66 ever had a right hand threaded extractor rod, so the L for left-hand threads on the cylinder would not be related to that change.

Your Model 66 would have been a no dash,

Early SS cylinders and dash 1 guns usually have a V stamp to distinguish the SS cylinder from carbon steel
in the raw in case they got mixed up prior to blueing.

My 66-2 has the letter F stamped on the cylinder face.

My dash 3 and up SS cylinders are not marked.

Jack is correct about the L stamp on the LH thread 19-1 cylinders, My 19-1 shipped in Nov 1962 and has it.

The L stamp continued into 1963 on early 19-2's but is gone by mid 1964 .

Guessing the L stamp was no longer necessary and discontinued after RH threaded cylinder supply was used up.

I suspect that is the case.

Yup, this Forum post was brought to you by the letter V .
