There are no markings on the receiver ring or between the rear sling swivel and triggerguard. There is the number 13 on the bayonet lug.First, you have a hybrid unofficially designated as a T-38/99 trainer. It has a T-38 configuration receiver (two gas ports) with a T-99 long configuration stock with the characteristic squared off forend. Brad is corrrect about the sling: it's not a commonly-encountered variant and is likely worth more than the trainer to certain collectors.
I'd be interested to know if it has an pistol grip markings, i.e., on the underside of the stock between the rear sling swivel and the tip end of the triggerguard tang. Also, the photo seems to indicate the lack of any receiver markings. Can you confirm?
Thanks. Will be tough for me to identify the maker w/o more markings. These unmarked trainers are, unfortunately, pretty common. However, the T-38/99 hydrids are a fairly uncommon variant.There are no markings on the receiver ring or between the rear sling swivel and triggerguard. There is the number 13 on the bayonet lug.
