BTW, the 1911 ALFA (Adolf Frank, Hamburg)export catalog "Arms of the World", page 453 offered several categories of Kar88 military configuration M88 carbines:
"entirely new made, case hardened bolt" with or without double set triggers, in 8x57I, 7x57 and 9x57. Prices fob Hamburg from US$ 95.- to 110.-.
Government surplus, 8x57 only, as is: $ 56.-
Government surplus,8x57, reworked, reblued and refinished $ 62.- with ds trigger added $ 72.-
So in 1911 new made M88 actions and carbines like the Mexican one shown by lancaster were still available on the commercial market.
