I once had a 12 ga Daly 500 with a 400,000+ serial number; way higher than the Dalys. It didn't have the 500 banner like Daly 500s do on the side of the receiver, but one of the barrels was roll stamped Daly 500. Through looking around, I found that that high of a number was the regular Miroku 500 gun.

To find the year of proof of your (Post 1975) Browning or Miroku shotgun you’ll need to find the Serial Number. On most over and under shotguns this should be situated under the top lever and on Semi-Autos somewhere on the receiver. In the Serial number there are two letters together - in the example above this is ZT - this your date code. With a hunting fore-end and automatic safety, the Miroku MK Game High Pheasant II is the type of gun you won't be able to wait to go hunting with. The engravings portray hunting scenes. PAIRS: 2 guns with consecutive serial numbers, matching wood, engraved I & II, delivered in a Miroku.

Miroku Shotgun Serial Numbers

FIREARMS INFORMATION

4 different style top leversprings are used, however in the only old parts catalog we can find, it isapparently for the type 2. They used the same part number for both thetype 1 and type 2, but differentiate only, Old Style or New Style and thegauge. Then later when the 3rd and 4th type came along, if there is anillustrated parts listing, no one has found it. The 4th type used coilsprings for the mainsprings, ejector hammers and the top lever springs. These coil springs proved quite a bit more reliable.

Here we cover mostly the O/U guns, however the single barrel trap guns are essentially an O/U with the bottom barrel missing

FOR OUR PURPOSES, UNTIL WE FIND MORE INFORMATION, WEWILL USE THEIR KNOWN PART NUMBERS ,
AS#2224 FOLLOWED BY THE FOLLOWED BY THE GAUGE AND THEN THETYPENUMBER
AS #2224-12-T1, #2224 -12-T2, #2224 -12-T3, #2224-20-T1, ETC.

TOP LEVER SPRING TYPE 4 #????	SERIAL NUMBERS #????
The information we can come up with is that possibly the last 2 years of production, 1975 & 1976, used coil type mainsprings, ejector hammer springs & the top lever spring. We also have seen guns that had broken top levers that were retrofitted with later top lever springs, or even retrofitted with complete coil springs.
