Model, calibre ?

Welcome to the Forum. You have a cheap copy of a Smith & Wesson revolver probably made in Spain , circa turn of the century era ( 1900 ) . I don't see any Belgian proof marks on the cylinder, so I'm going with a possible Spanish made gun, or could even have been made in So. America. Show better pictures of the rear of the cylinder, with comparison items, to estimate caliber. Calibers of these guns vary quite a bit from .38 to 11 MM, but many will chamber various .44 cal rounds from .44 Russian to 44-40 WCF. The logo on the top of the grips is the makers logo, assuming the grips are original to the gun, however I do not find a listing of that symbol for a European maker in any of the books on grips markings. Hopkins & Allen, an American maker of quality firearms used a similar logo, so the grips may be a replacement. Ed.

My English is limited. Thank you for the information . added new pictures.

The dog head grips appear to be from a Hopkins & Allen revolver (or a very good copy). However, as Ed mentioned, the barrel markings are not from a US made revolver.

The Euscaro Revolver (Zhuk 593) was made by both Orbea Hermanos and Crucelegui Hermanos of Eibar, Spain. Caliber is probably .38 S&W, based on the proportions of the gun and the barrel rib inscription.

The 1911 ALFA catalogue shows the type, complete with dog's head grip logo under "System Smith & Wesson" cat no 305. Price at the time ranged from 13 to 28 German Marks, depending on caliber and finish. The more expensive versions had pearl handles which seem to have added a lot to the price.
