In the 1970 catalogue they show the Model 500E (BLE) and the 500 (BLNE) is mentioned but not the weights.

In the 1976/77 edition there is mention of the “new” MS-150 which is better described in the above 1981 entry where the weight is given as approximately 6 1/2 pounds.

Miroku have always had an excellent reputation for quality.

Post pictures of the British Proof Marks when you gun arrives and we can probably establish the year it was imported.

I had a 500. Good skeet gun.
