A little bit of history about the BRNO .22's:
CZ in Czech (Ceskoslovenska Zbrojovka; often abbreviated as Ceska Zbrojovka) roughly translates to "Czech Arms manufacturer". They added the town name after the CZ so you had entities like CZ UB (Uhersky Brod) and CZ Brno (Brno), etc. These were Govt. facilities so they would be similar to IOF Khadki or IOF Kanpur, etc.
BRNO started making the ZKM452 (model 2) in 1956. About 1967, production was switched to CZ UB, but still stamped "BRNO." Originally CZ putting together Brno made parts, under Brno inspectors. In about 1974, CZ started manufacturing the rifles at Uhersky Brod. I'm not sure when the BRO name was dropped. CZ UB still makes the model 452, though there have been some changes, like the plastic magazine, etc. So technically, what was the BRNO model 2 is still being made. The BRNO model 5 would be similar to CZ's Model 455.
Rifles stamped BRNO are still in demand in places like South Africa and India. In the US there are still a few collectors of BRNO rifles. While CZ makes fine rifles upgraded to use the latest manufacturing methods and better steels, etc. they are considered middle of the road rifles. Increased competition in the USA and the availability of many different makes and models of rifles makes this so. This should not detract from CZ current offerings as they are well made and renowned for their accuracy. There is some recognition, in the US, that the rifles were decent. However today's rifles are made with better materials and manufactured to tighter tolerances.
I can't really comment on prices in India but in the US you can buy a Model 452 Scout for about $300 (brand new). A CZ Model 452 Special Military Training Rifle goes for $395, a CZ 452 Ultra Lux for about $410. These prices are MSRP and street prices would probably be lower. Of course, used .22 LR CZ rifles would be priced lower unless they were a special run or a rare model. Used BRNO .22 LR rifles are not that desirable here. You can but a used BRNO branded ZKM468 for $179. Christies sold a BRNO model 2 with a scope for $135
A used Anschutz sporting rifle, on the other hand, would go for $800/900 and up. So the desirability and price are significantly higher. Are they that much better as a rifle or does the Anschutz name give them a special cachet? Some people apparently think so and are willing to pay for it. Used BRNO marked centerfire rifles, however, are in demand and some models and calibers would go for several thousands of dollars.
My advice, for what it's worth, would be to get an Anschutz .22 LR instead of the BRNO model 2 if you can make the deal. Please also keep in mind that a 40 year old .22lr rifle in pristine shape quite possibly is refinished and not original (finishwise). As far as the Remington model 700 rifle in 30-06 (in India) is concerned; there would be a huge demand for it. Most likely it will fetch more than a .22 LR rifle. Don't let the dealer hoodwink you. Please let the Capt, Doc and Dr JK guide you in that matter.
