It took me a bit, but I finally remembered that I had two Prussian Dalys in the serial number range we are discussing down in the safe.

#347 is a Daly diamond quality model 250. It has the crown over crossed pistols.

#481 is a Daly Featherweight two-barrel set (in 20 gauge!!). It is marked with the HAL of crossed pistols.

I am with you Raimey on the hypothesis that the overlapping HAL/crown marks are likely due to the vagaries of production timelines. Unfortunately only one of the HAL guns in question (Daryls) has the model noted. When the Daly database was first started by Michael Petrov, many of the early entries only noted the serial number and maybe a few other details. Over time, additional fields were added to the database.

#270 though is noted as a "lower grade gun" and possessing the HAL. The others - 272, 299 - do not have a model provided.

On the crown-marked guns, only the 3XX gun has any details. It is noted as a "mid-grade gun."
