He writes;
Capt. v. Blumen auf 4 Monath beträgt 132.
Means [the outstanding pay for himself] for 4 months sums up to 132 [Reichsthaler].
The monthly pay for a Stabs-Capitaine was 30 Reichsthaler (a real Capitaine would get 100 Rth., a Premier-Lieutenant 25 Rth.). I don't know where the additional 2 Reichsthaler, or 12 Groschen per month, come from.
