Am guessing you do not need insurance advice. I hate things like this, hope you list everything with Leica and who ever to possibly regain some of your stuff, the cops should circulate the numbers to the local pawn shops, but I would post in several forums the stolen items.
I agree that vintage lenses can often need TLC, and hard to knock the CV 50mm, especially if you fall in to a good price. If you watch the classifieds here like a hawk, or post a WTB, you might have some luck, but often things go very fast.
I saw that Igor at
www.igorcamera.com had a CV 25 LTM with finder on his table last camera show, he probably will price it low enough with the Bessa L attached as to make the extra body free, or available to sell on the side.
If you email him, he might be able to watch for some glass for you, I have not checked his website lately, but he is one of the good people to buy used from, anything he has will more than likely be very well documented as to condition, and he has several repairmen to cla his stuff.
I have seen the KEH buyer, John, at a show where he bought $70,000 worth of walk in equipment, and the first thing she does with lenes is put a flashlight on the back and check for haze, etc. They buy to maintain an inventory, and if you see something there, you can buy and send back if it is not right for you. Same really with Igor and all the big name places, B&H, Adorama.
So it is a bit of a hunt for you. If you do buy the CV 50mm, am pretty sure it is such a well liked lens you can easily get your money out of it at some future date if you want to trade up, OTOH, I have one, my friend Jorge has one, and I hear a lot of good all around, a modern design lens at a modest price.
Am not sure if Stephen (head bartender) has any left in stock.
I would also recommend the CV 35mm 1.2 if you find a price you like, M mount, very popular and respected lens. Newer ones all were modified slightly for the M8, a rear piece had to be replaced.
I think the 90mm 2.8 Leica glass is generally modestly priced.
Bottom line, for reasonable modern glass, hard to beat CV. Regards, John
