Well whatdoyaknow I have one.
Amazing what you will find in the back of the safe
Apparently they are still manufactured as a model 24
And there is one over at Gunbroker listed at $295 I believe it is listed as "as new" or excellant condition
There is another one with a rusty barrle and some pitting listed at $150
Those book prices I gave are merely starting points and the authors opinions.
Are you looking to sell or just for historical information
For historical info you can write and send $15 per gun to
