MBWT Data Comparisons (Damascus and Fluid)

[Dean Weber]

Edgar,
I would like you to share your numbers as well!

Your point is very valid and clear when you study like, original guns next to each other they provide for an interesting discussion. For example subjects 10 and 11. Both are original guns on a 1 frame (1 28" and 1 26"). The 28" weighs 5oz less than the 26". They have similar MBWT. Yet the 28" chamber/fc measurement is .020 less. One has a steep FC and the other a more gradual one of a few thousandths.

The 1907 Hunter Arms Chamber Specifications drawing shows the forcing cones as slightly less than 1/2" and a straight taper. The cone angle was shallower in the 1935 drawings with a length of about 5/8".

Austin Hogan stated that, at least early on, the Parker cones were cut at a Ogee rather than a simple taper; this illustration is obviously exaggerated. I've been looking for his posted WT numbers in my files without success.



Was this cone profile continued throughout production?

Austin’s research also indicated the chokes were cut (or bored) at an ofee as well and he believed from the many Parkers he examined that this practice continued until Remington cut the chokes at an angle rather than continue the more precise and labor intensive practice of cutting them at an ogee. I don’t know if this also applies to the chambers/cones.

I have a 1904 CHE 16 O-frame gun. It weighs a smidgeon over 6 lbs. (research letter also indicates this weight). The unstruck barrel weight is 3 lbs 1 oz. Actual weight is 2 lbs. 8 oz. Its barrel measurements (Hosford gauge for wall thickness measurements) are:

R/L:
Bore -- .666.,665
MWT @ Chamber -- .098/.092
MWT @ 9" from breech -- .040/.042
MWT @ 9" from muzzle -- .025/.033
MWT -- .025/.031

I had a complete set of Hayes’ choke reamers which were straight tapered.

Austin was meticulous in his plotting of the measurements of chambers, bores and chokes he measured. Here he supports his findings of forcing cones and chokes having been cut to an Ogee.

I took these picture of some of the pages in his notebook. You'll notice that most of them are identified with serial numbers and some are right into the 1920's.

Parker, 28" DHE 16ga. 0 frame, Made in 1898. Wgt 6/6
Damascus; Unstruck wgt 3/7, Finished wgt 2/12
MWT, .024"R, .024"L
MWT 9" from Breech, .046"R, .045"L
MWT 9" from Muzzle, .025"R, .024"L
MWT-Chamber, .095"R, .099"L
MWT-FC, .104"R, .107"L
Bore, .666"R (must be Satanic Steel), .665L

I'll double check these later, rule out my hand tremor.
