The problem may be that you expect them to be there under their names:
they're not. -est use estimates, number(1)- just brings back the first
saved estimates as the current estimates, not under the name it was
stored as. 

This code should make that clear:
----------------------------------------------------------------------
sysuse nlsw88

// Fit, store and save a set of estimates
reg wage ttl_exp
est store model1
est save estimates

// Do the same with a second model
reg wage ttl_exp i.collgrad
est store model2
est save estimates, append

// Drop the estimates
est dir
est drop *
est dir

// Pull them back in:
est use estimates, number(1)

// Note the estimates come back but not stored under their names
est dir

// But they're accessible:
reg

est use estimates, number(2)

reg
----------------------------------------------------------------------

If you really want to have stored estimates, you can do something like
this (in a loop, obviously):
----------------------------------------------------------------------
est use estimates, number(1)
est store model1
est use estimates, number(2)
est store model2
----------------------------------------------------------------------

Brendan
