I checked with Monk on a trade label for my gun a couple of years ago and was informed that they were not available.
If you have better luck finding one now, please let me know.
By the way, Monk told me that they serial numbered their guns of that era with the year that they were built followed by the number designating the order in which the gun was built that year. For example, 193411 would be the eleventh gun built in 1934.
And my gun was not actually made by Monk, it was built for them in Birmingham.
