To help you put things in perspective, I bought a really nice 99H carbine in 30-30 through the Fire Classifieds a little over six months ago for around $450. Great bore, no cracks or extra holes, flawless function and no scratches or gouges in the wood. No rust or pitting. Metal has a very nice patina. DOM is around 1926. Looks great. Shoots great.
For my money, if you are looking for a 99 in 30-30 (the 99H carbine is a sweet, great handling rifle) I recommend you pass on the rifle you are considering and let the guys on this forum know you are in the market. Long term I think it will be money saved and you will have a nice rifle you can be proud of.
BTW, mine is not for sale.
Just my two cents. - T.S.
