Recently bought a older 20 ga. sxs boxlock. 28" barrels Mod. & Full. Marked as follows Mercury Magnum Model G2028, S/N 102XX, G, LIG.
Smooth mirror barrels, good blue,nice wood, no cracks. Shot 100 rounds this past weekend. Seems to be in good mechanical condition. The double triggers are 3-3/4 and 4-1/4.
Referencing the Terry Wieland book, "Spanish Best" I identified the following marks. Page 316 marking #18, marks used from Dec. 14, 1929- July 9, 1931. Page 317, #21 and page 317 #25.
Interesting that proof marks #18 and 21 are between the dates Dec. 14, 1929 and July 09, 1931. Proof marks #22 and 25 are since July 9, 1931.
Would anyone know who the Spanish Mfg. was?
