HELP TO IDENTIFY THIS AIR RIFLE

[Juaristi]

I need help from more learned airgun users here .
Has anyone any idea what this air rifle is ?
Pneumatic - pump-up ( like the Sharp Innova system ) .
Steel fabrication not alloy ( except the unusual muzzle break with the foresight placed onto it and not the barrel ) .
Real wood - looks like Mahogany .
Pellet loading by old style pellet lever ( similar to British made BSA from the 1900's ) .
Age - possibly 1970's/80's ?
There are NO MARKINGS anywhere !!!
Not British , Not USA so Indian manufacture ? Or South American ?

Possibly Indian. Can you post some more images. Any mark or logo is printed on the gun??? And what calibre it is??

Hi ,
it is 4.5mm , and with no markings ! Unusual , and confusing .
System - pneumatic pump , rearward action
- different operation but very similar pump rod system to the Sharp Innova , Ace , Benjamin and some Crosman models
Bodywork
- All steel metalwork , with an alloy shroud or silencer -
Note - the foresight blade is set within this - have never seen this on any other airgun
Woodwork
- good quality Mahogany ( Or low grade Walnut ) unlike the many EU/UK/Turkish made items with white wood / Beech wood.
Pellet loading
- by traditional old style tap lever to the left side .
So -
a mix of styles , made to a very high quality in steel . Old 1950's BSA / Webley pellet loading ' tap lever' style matched with a more recent 1980's pneumatic pump charging system .
I thought South American / Spanish origin but then thought of India .........over to the Indian experts here !
